CTR 38 GHz Release 1.2 1-7
Reunion CTR 38 GHz Installation Guide
Low Noise Amplifier
The low noise amplifier (LNA) provides gain in the receive path and
amplifies the received microwave signals to the mixer. The gain and noise
figure of the LNA are chosen to maximize the overall dynamic range and
noise performance of the CTR 38 GHz receiver section.
Power Amplifier
The power amplifier provides gain in the transmit path. It boosts the signals in
the 38.75-38.95 GHz frequency range to the required level. The amplifier is a
solid state amplifier that has high linearity within a high output power range.
Duplexer
The CTR 38 GHz uses the duplexer to combine and separate the transmit and
receive RF signals, allowing use of a common antenna for receiver and
transmitter.
Antenna
The CTR 38 GHz uses a reflector antenna to transmit and receive RF signals.
The CTR polarity must be polarized with the BTR polarity. The CTR 38 GHz
operates only in a vertical or a horizontal polarization.
Note: V= vertical TX wave polarization
H= horizontal TX wave polarization
Note: Lightening arrestors are not supplied with the CTR transceiver.
