MICROSET - VUR 30 - DUAL BAND AMPLIFIER 144 + 432 MHz - FULL DUPLEX - LOW NOISE GaAsFET 16-15 dB RX PREAMPLIFIER 

FULL-DUPLEX DUAL BAND AMPLIFIER 2 m - 70 cm
DUPLEXER INSIDE - DUAL STAGE AMPLIFIER
Double low-noise GaAs FET preamp stage

The MICROSET is the first and only linear amplifier with internal duplexer and GaAs FET preamplifier able to operate in full duplex. In fact, thanks to its special and exclusive technology and configuration it can work without introducing appreciable distortions with only one antenna. The positioning in the desired band is completely automatic because a memory circuit retains the command and band errors can not occur; this occurs both for full-duplex and simplex operation and is also used for single band with the possibility of operating in S.S.B. In addition to the excellent operational capabilities, the VUR 30 also stands out for its structure, compact dimensions, professional construction concept, Mil Quality components and for the many tests it is subjected to during assembly and testing, ensuring a long and efficient activity.

• FREQUENCY 144-148 / 430-440 MHz
• FULL DUPLEX
• INPUT 1-6 W (FM)
• 30W OUTPUT (VHF) 28W (UHF)
• GAIN PREAMP. 16 dB (VHF) 15 dB (UHF)
• NOISE 1 dB (VHF) 1.2 dB (UHF)
• POWER. 13.5V 4A
• DIMENSIONS AxLxP 50x105x220 mm

RF CONCEPTS - 2/70G - VHF/UHF AMPLIFIER with GaAsFet receive preamplifiers - 143-149 30W max. out / 430-450 MHz - 20W max. out 

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.

RM ITALY - HLA150 PLUS - LINEAR AMPLIFIER 1.8-30 MHz - ALL MODE - OUTPUT POWER 250W p.e.p. SSB MAX. - 12-14 VDC

NEW "BLACK" SERIES - ALL BLACK COLOUR

MAIN FEATURES
Ideal for QRP rigs.
Protection against polarity reversal, excessive temperature and excessive S.W.R.
PTT connector
Output power indicator
6 output low-pass filters that can be inserted manually or are controlled by a microprocessor, with a cut-off frequency of 3 / 4.5 / 8 / 15 / 22 / 31 MHz, to drastically reduce harmonic emissions. The filter selection control can be automatic, controlled by a microprocessor that reads the transmission frequency and automatically selects the appropriate filter, or manual (selection of the band through the switch located on the front): in the latter case the microprocessor checks that the filter selection is correct; possibly signaling through an acoustic warning the possibility that the filter set is incorrect.
A temperature sensor blocks the operation of the amplifier and emits a warning signal, if it becomes excessive; the reset is automatic when the temperature returns to normal functional parameters.
A SWR protection circuit blocks the operation of the amplifier in the case of a high level of stationary waves; the same circuit protects the amplification stage from the possibility that an incorrect selection of low-pass filters may damage it.
