(3) Transceiver

 

Transmitter

High power MOS FET amplifier with 10-step power reduc-

 

tion switch

Receiver

Low noise superheterodyne, continuously scanning beam

 

forming, TVG, AGC, signal/processing, interference rejec-

 

tor, horizontal vertical beam switching.

(4) Beamwidth (-3 dB) and Tilt Angle

TX Beamwidth

360° (horizontal) x 13° to 16° (vertical)

RX Beamwidth

9° to 18° (horizontal) x 13° to 16° (vertical)

Tilt Angle

-5°(upward) to 60° (downward), continuous.

 

NOTE: Beamwidth depends on transmitter frequency.
