RF Power Transistors

RF Power Transistors are discrete, single gain stage semiconductors that can be optimized to develop customized RF Amplifier circuits. Richardson RFPD supports the largest offering of RF power transistor technologies, including silicon biploar junction, silicon RF MOSFETs, silicon RF LDMOS, and GaN HEMT transistors. Most devices are unmatched or partially matched to 50-ohms, but several impedance matched FETs (IMFETs) are available from Richardson RFPD.
