* Extensions or changes of the frequency coverage are possible on request.
** Please refer the applicable region bandplans and laws for specific allocations and limitations.
b) Rated output power: 700W +/-0.5dB, PEP or continuous carrier.
c) Intermodulation distortions (IM3): better than 31dB below the rated PEP.
d) Harmonic and parasitic emissions output suppression: better than 60dB (65dB typically).
e) Input and output impedances:
- nominal value: 50 Ohm unbalanced, UHF (SO239) type connectors;

Functions

a) Receive / transmit control:
- KEY-IN input – Phono RCA jack; voltage applied to the transceiver keying output up to +12V;
current drawn by the transceiver keying output up to 6mA;
- An optional KEY-OUT output – Phono RCA jack; output resistance: not more than 120 Ohm;
maximum safe input voltage from the transceiver +50V; maximum safe current drawn by the
transceiver: 20mA;
minimum dead time, necessary for safe amplifier switchingover from receive to transmit: 10ms
-
between the transmit request on the KEY IN input and the RF drive on the RF INPUT jack.
