Preliminary - Subject to Change Without Notice
This version of the block diagram does not attempt to show
the interconnectins between the receiver/exciter, the power
amplifier, and the antenna coupler.
This version of the block diagram corresponds to the content
of Technical Specification Rev C, January, 2002.
1.B. 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 Hardware (optional)
1.B.(1) KAC 1052 Antenna Coupler
(P/N 064-01074-0001)
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 a high frequency power amplifier. From 2.0
to 29.999MHz, the power amplifier is capable of linear
amplification of a 0dBm signal to a 200 Watt output level
at 50 ohms input and output impedance.
1.B.(3) KRX 1053 Receiver/Exciter
(P/N 064-01073-0101)
The KRX 1053 is a high frequency receiver/exciter that is
designed to operate from 2.0 to 29.999MHz synthesized in
100Hz steps. The unit will operate Amplitude Modulation
Equivalent, Upper and Lower Sideband modes and
Required-Carrier mode.
