System Component Descriptions
The required and optional equipment of a KHF 1050 HF Communication System is
listed below:
KAC 1052 Antenna Coupler (required)
KPA 1052 Power Amplifier (required)
KRX 1053 Receiver/Exciter (required)
Compatible HF Control Display Unit (required)
Mounting Tray for the KAC1052, KPA1052 and KRX1053 (required)
1.B.(1)
KAC 1052 Antenna Coupler
(P/N 064-01074-0101)
Under microprocessor control, the KAC 1052 antenna coupler selects tuning
network configurations, impedance transformations and binary capacitance
and inductance to produce a VSWR of 2.5:1 or less upon initial tune. The
VSWR may then deteriorate to 3:1 before the coupler will retune when transmit
is next initiated.
1.B.(2)
KPA 1052 Power Amplifier
(P/N 064-01072-0101)
The KPA 1052 is an HF power amplifier. From 2.0 to 29.9999 MHz, the power
amplifier is capable of linear amplification of a 0 dBm (1 mW) signal to a 53 dBm
(200 W) output level at 50 ohms input and output impedance.
1.B.(3)
KRX 1053 Receiver/Exciter
(P/N 064-01073-0101, -5101)
The KRX 1053 is an HF receiver/exciter that is designed to operate from 2.0 to
29.9999 MHz in 100 Hz steps. The unit will operate Amplitude Modulation
Equivalent, Upper and Lower Sideband modes and Reduced-Carrier mode.
1.B.(4)
PS440 Control Display Unit
(Honeywell P/N 071-01605-0101, -0201, -1101, -1201, -2101, -2201)
(Gables P/N G7511)
The PS440 stand-alone HF COMM Control Panel is designed to provide control
of a single or dual HF COMM radio system. Full operational control of the HF
system is accomplished via a dedicated low speed, digital ARINC 429 bus.
