The 20W-VHF amplifier from the Italian company ABE Elettronica is a top-of-the-line signal amplification module, designed for continuous and demanding operation in broadcast systems.

It is an integrated unit (Pallet) placed inside a specially processed shielded aluminum chassis, which offers maximum protection against interference and excellent thermal behavior.

Main Features:

BLV33 Technology: It is based on the legendary BLV33 power transistor (Philips/NXP), which is renowned for its linearity and durability in professional broadcast environments.

20 Watt Power: Optimized for 20W output in the VHF band, offering a stable signal with a high degree of purity.

Shielded Construction: The robust aluminum box with the screw cap ensures complete RF protection (EMC Shielding), making it ideal for installations with multiple transmitters.

High Precision Connections: Features inputs and outputs with SMA type connectors to minimize losses and easy interconnection.

Thermal Management: Includes external power resistors to stabilize the circuit and is ready to fit a heat sink.

Ideal for:

Repair or upgrade of TV and VHF radio transmitters.

Laboratory RF amplifiers.

Signal relay systems.
