Product Overview: Control-Head Assembly 2.3.2.5 VIP Output Connections: There are three VIP outputs that are used for the W9 control head and two VIP outputs for the W3, W4, W5, and W7 control heads. The VIP outputs are normally at SWB+ levels and are driven low by logic within the control head for both the dash- and remote-mount configurations.
Product Overview: Control-Head Assembly 2.3.2.7 DEK Interface With Radio: Remote-Mount (W4, W5, W7, W9) A maximum of three DEKs can be daisy chained to a single mobile radio. DEKs are only used with the W4, W5, W7, and W9 control heads when they are remotely mounted on the radio. DEKs are not used with any dash-mount control heads, including W4, W5, W7, or W9.
Product Overview: Receiver Section Receiver Section This section discusses the receiver section components and basic operation for each band. 2.4.1 VHF Band Radios The VHF (136–174 MHz) receiver consists of a front-end and a back-end sections. 2.4.1.1 Front-End Section The primary function of the receiver front-end is to optimize image rejection and selectivity while providing the first conversion.
Product Overview: Transmitter Section The back-end is primarily the ABACUS III digital IC. The ABACUS III IC uses a variable-bandwidth bandpass sigma-delta architecture. It is capable of down-converting analog as well as digital RF protocols into a baseband signal, which is then transmitted over the Synchronous Serial Interface (SSI) bus to the DSP and microprocessor.
2-10 Product Overview: Frequency Generation Unit 2.5.3 700–800 MHz Radios The 700–800 MHz transmitter consists of an RF power amplifier (RFPA), output network (ON), and power control. 2.5.3.1 RFPA The RFPA is a three-stage, discrete-LDMOS transistor amplifier consisting of the following stages: first, driver, and final.
Product Overview: Frequency Generation Unit 2-11 • Associated circuitry The reference oscillator IC provides a frequency standard to the Fractional-N synthesizer IC, the ABACUS III digital back-end IC, and the controller section. The synthesizer turns on one of the four VCOs (determined by mode and band of operation) and tunes it to the receiver (RX) local oscillator (LO) or transmitter (TX) carrier frequency.
2-12 Product Overview: Controller Section The voltage-controlled oscillator (VCO) module employs a Colpitts configuration with two bipolar stages in a common-base, common-collector configuration. The LC tank circuit's capacitive portion consists of a varactor diode, coupling capacitor, and a laser-trimmed capacitor for frequency adjustment.
Product Overview: Controller Section 2-13 2.7.2 Digital (ASTRO) Mode of Operation In the ASTRO mode (digital mode) of operation, the transmitted or received signal is limited to a discrete set of deviation levels, instead of continuously varying. The receiver handles an ASTRO- mode signal identically to an analog-mode signal up to the point where the DSP decodes the received data.
Page 66
2-14 Product Overview: Controller Section The DSP section of microprocessor performs signaling, voice encoding/decoding, audio filtering, microphone gain and tuning, Private-Line/Digital Private Line (PL/DPL) encode, and alert-tone generation. It processes all baseband audio signals, providing pre-emphasis and signaling/filtering of the digital microphone audio data, as well as other transmitted signals. It also performs de-emphasis and decoding of received digital speaker audio and other received signals.

Theory of Operation: Receiver Front-End 3-15 3.4.1.5 Mixer (D3258) The received signal is down-converted by a double-balanced mixer to an Intermediate Frequency (IF) of 109.65 MHz. The mixer is designed to provide low conversion loss and high intermodulation performance. The injection buffer provides a 20 dBm LO signal to the mixer. High-side injection is used.
3-16 Theory of Operation: Receiver Front-End 3.4.2.1 Highpass Filter and First Low-Noise Amplifier The highpass filter and first low-noise amplifier (LNA) (11 dB gain) can be switched in and out of the signal path by diode switches. When switched into the signal path, the sensitivity of the radio is improved at the cost of degraded intermodulation performance.
Theory of Operation: Receiver Front-End 3-17 3.4.3 UHF Range 2 (450–520 MHz) Band The receiver circuits primary duties are to detect, filter, amplify, and demodulate RF signals in the presence of strong interfering noise and unintended signals. The receiver (see Figure 3-15) is broken down into the following blocks:...
3-18 Theory of Operation: Receiver Front-End 3.4.3.2 Preselector Filter The front-end operates in the 450 to 520 MHz band. The front-end's primary function is to optimize half IF rejection, image rejection, and selectivity while providing the first conversion. The front-end uses a varactor-tuned filter that is tuned by the controller.
Theory of Operation: Receiver Front-End 3-19 3.4.4 700–800 MHz Band The receiver circuits primary duties are to detect, filter, amplify, and demodulate RF signals in the presence of strong interfering noise and unintended signals.

3-20 Theory of Operation: Receiver Back-End 3.4.4.3 Mixer (U6251) The monolithic, passive mixer IC down-converts the received signal to an Intermediate Frequency (IF) of 73.35 MHz. The mixer is designed to provide low conversion loss (< 7.0) and high intermodulation performance. To improve the performance of the mixer in both bands, a shunt 9.1 pF capacitor (C6297) along with a resistive PI network (R6278, R6280, R6281) is designed at the IF port (pin 5) of the mixer.

3-22 Theory of Operation: Receiver Back-End 3.5.2.1 Intermediate Frequency (IF) Filter The XTL 5000 radio uses two leadless, surface-mount, two-pole, third-overtone, quartz crystal filters (Y5400, Y5401) separated by a 20 dB gain IF amplifier. The filter is centered at 109.65 MHz. This narrow-bandpass filter gives the radio part of its adjacent-channel and alternate-channel rejection performance.
Theory of Operation: Receiver Back-End 3-23 3.5.2.2.1 Second Local Oscillator (LO) The ABACUS III IC local oscillator (LO) synthesizer controls the second LO. Signal FREF is the 16.8 MHz reference from the frequency generation unit (FGU). The second LO frequency is 107.4 MHz by default, or 111.9 MHz in special cases as necessary to avoid radio self-quieters.
Theory of Operation: Receiver Back-End 3-25 3.5.4.1 Intermediate Frequency (IF) Filter The XTL 5000 radio uses two leadless, surface-mount, two-pole, third-overtone, quartz crystal filters (B6350, B6351) separated by a 20 dB gain IF amplifier. The filter is centered at 73.35 MHz. This narrow-bandpass filter gives the radio its adjacent-channel and alternate-channel rejection performance.
