23cm GaAs-FET preamplifier by YO5OFH 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. This particular design is not very different from the common ones.https://www.qsl.net/yo5ofh/projects/preamplifiers/23_cm_gaas_fet_preamplifier.htm
435 + 1296MHz ATF54143 Pre-amplifier by GØMRF The ATF54143 is a PHEMT device from Agilent technologies that can provide low noise figures combined with high signal handling characteristics.http://www.g0mrf.com/432LNA.htm
