6m Preamp - A dead easy 50 mhz preamp by VK3CJS

Garex VHF preamp - It is available for spot frequencies in the range 40 - 250MHz, where a typical gain of 26dB can be achieved

144 MHz preamplifier with BF981 - Design of a preamplifier for 144 MHz with 1 dB NF and 23 dB gain using BF981. This amplifier is using a low cost silicon MOSFET (BF981 from Philips) to give more than 20 dB gain with around 1 dB noise figure on 2 meter.

LNK Receiver Preamp - It is tempting to hope that a preamp can make any receiver more sensitive, in any situation. But, it is important to understand what happens when you add a preamp before a receiver.

23cm dual stage preamp - A modification / combination of the DJ9 BV & I5TDJ 144 MHz preamp designs

U301 FET preamplifier - This FET preamplifier has been around for almost 25 years. It is extremely reliable and can handle several watts directly into either the input or the output without failure.

23 cm GaAs FET preamplifier - On 23cm the best way to obtain a good RX-sensitivity is to use a GaAs-FET in the front-end, since these devices show very low noise figures.

GaAs FET preamps - Build a good GaAs FET preamp for 2 meters, 222 or 440 Mhz

Receive only processing equipment - One of our most popular products, receiving preamplifiers are used for achieving top signal band performance in competition operating, low noise longwave reception, repeater applications into the UHF region, or lab use
