BEKO HLV-523 (1270-1300 MHz) RF Power Amplifier




BEKO HLV-523.                23 cm RF Power Amplifier

“Designed for the serious Weak Signal, EME, Digital, & Contest Operation!”

The BEKO HLV-523 employs advanced German-engineered, solid-state technology to deliver instant on, no compromise performance.  The HLV-523 features full mismatch load protection by an integrated circulator. In addition, the RF output relay can be included for additional cost.

The HLV-523 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-523 Features:

* 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

* Drive power is 7 watts nominal.

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.
