RF CONCEPTS - 2/70G - VHF/UHF AMPLIFIER

Description

RF CONCEPTS - 2/70G - VHF/UHF AMPLIFIER. Condition is "Used". Shipped with USPS Priority Mail.
The RFC 2/70G is a dual-band power amplifier and dual-band receiver pre-amplifier combined as one.
The main features are automatic keying and amplification of RF energy from your dual-band hand-held (HT).
When the HT power output is sensed by either the 2-meter or 70-cm narrow band peak detector, the preamp is switched out and the power amplifier is switched on.
The two front panel switches allow for independent selection of the power amp, pre-amp or both.
The RFC 2/70G features two GaAsFets as the pre-amplifiers, one for each band.
FETs provide good gain and noise figure.
An added feature is the addition of PIN diodes as protection circuitry at the front-end and output of the FETs.
In addition, the RFC 2/70G features fast coaxial relay switching, generally less than 20 ms.
The relays are 50-ohm compatible, sealed and require low power to latch and control, making the RFC 2/70G ideal also for high-speed packet applications.
