Solid state power amplifier trio head to the UK
Distributor Aspen has added Exodus Advanced Communications to its portfolio. The Nevada-based company offers laterally diffused MOSFET (LDMOS), GaN, GaAsFET discrete and chip and wire hybrid technologies with amplifier designs covering octave through decade frequency ranges from 0.01MHz to 40GHz. Power levels exceed 1kW for modules and 10kW for rack mount amplifiers.
Of initial interest, says Aspen, will be the range of high power solid state power amplifiers (SSPAs). The distributor offers three. The AMP1025 model covers 20 to 1000MHz. The compact 70W broadband module uses Class AB linear LDMOS devices with 5mico sec on/off switching speed. It has a large signal gain of 48.5dB minimum and a Psat output power of 70W minimum (80W typical). The two-tone intermodulation (IMD) is over 30dBc typical.
The AMP1021X2 is a compact (60 x 50 x 11mm) GaN-based amplifier covering the frequency range 225 to 2600MHz. With a Psat output power of 7W minimum, 10W typical, plus a gain of 39dB, the current draw is just 1.4A typical. Weight is just 57g.
Lastly, the AMP2035 is a 6.0 to 18GHz, 10W ultra broadband system, featuring Class AB linear GaAs FET design in a small and lightweight benchtop chassis. Power output is 10W minimum with a large signal gain of 43dB minimum and two-tone IDM of above 30dBc typical.
