Description

BEKO HLV-770-LPD       70 cm RF Power Amplifier (low power drive)

“Designed for Weak Signal, Tropo Scatter, Meteor Scatter, Digital, & Contest Operation!”

The BEKO HLV-770-LPD employs advanced German-engineered, solid-state technology to deliver instant on, no compromise performance.

The HLV-770-LPD is the ideal amplifier for contest, portable, EME & home station operation due to its small foot print and light weight.  BEKO amplifiers are “the best of the best” VHF UHF & SHF high-power linear amplifiers available worldwide!

HLV-770-LPD Features:

* This amplifier is designed specifically for use with low RF output drive level SDR transceivers.  This amplifier includes a high linearity, 37 dB gain driver stage operating at 48.0 VDC and user adjustable input attenuator to set low level RF drive from 0 to 10 dBm for full RF output power.

 

* Instant on, no warmup is needed.  Don’t miss the opening!

* No tuning required

* WSJT / FT8, Digital Mode at rated output

* New, super-fast, accidental-overdrive / spike protection up to 150W

* Built-in IMD indication

* Extremely High efficiency

* VSWR, overdrive and temperature protection

An integrated sequenced voltage to control external mast-mounted preamplifiers is provided. A built in Bias-T allows the preamp voltage to be injected onto the coaxial cable. For those preamplifiers that can’t be powered via the coax and require a separate VDC cable, the sequenced voltage is available via a back panel connection.  As with all Beko Elektronik amplifiers, a front panel switch allows the user to select external preamp on/off function thus allowing the preamplifier to be switched in-line or off-line.  See us for suitable mast-mounted preamplifiers.  The HLV-770-LPD provides a direct connection to the BEKO 2.5 kW mast-mounted preamplifier.
