RF amplifier with tuner
PA500 linear amplifier with integrated automatic antenna tuner for your next adventure
Ideal addition for QRP operation and digital emergency radio communication
The complete solution to conquer limitations
automatic band selection
compatible to most Transceivers
made for HAMs
tailored for adventures and extremes
signatured aluminum body
robust outstanding quality
covers most HAM SW Bands
RF Power up to 60W
integrated automatic tuner
we really like the Discovery TX-500 Transceiver from Lab599. The PA500 is basically made for the TX-500 but it will work nicely with other Radios as well. The thickness of the PA500 is just 30mm and allows you to operate from anywhere you like.
RF Low pass filters
the PA500 has separate low pass filter banks for the specific band regions. RF Filters made with superior ferrite toroidal cores and precision high voltage capacitors. The harmonic distortion suppression are >43dB below the carrier signal depends on the selected frequency band.
power on the go
the BAT500 with 51.2Wh LiFePO4 battery storage is a unique addition to the PA500 amplifier. The System consisting of a high efficient HF amplifier with an antenna matching tuner and a robust energy source that can be charged with solar panels (e.g. from PowerFilm), is a complete solution for all radio outdoor activities and for off-grid emergency communications. With only 660g (1,46 pounds) and a robust CNC made aluminum ewnclosure, this power-pack is a perfect addition.
robust aluminum body design
The PA500 body is made of CNC milled durable anodized aluminum, made for extreme operation, perfect for contest work on the go.
integrated automatic antenna tuner
the PA500 has an integrated automatic antanna tuner for most of the operating frequencies to tune a suitable antenna between the 80m and 10m band.
