A novel high-power MMIC amplifier provides a simpler alternative to multichip modules, thus helping to reduce the complexity and cost of communication subsystem designs.

New from RF and microwave component specialist Link Microtek is a high-power MMIC amplifier that provides a simpler alternative to multichip modules, thus helping to reduce the complexity and cost of communication subsystem designs.

Manufactured by TriQuint Semiconductor, the TGA4905 is a 4W device aimed at Ka Band digital radio applications such as LMDS systems and point-to-point radio, as well as VSAT and other types of satellite ground terminals.

The amplifier's operating frequency range is 25-31GHz, and it delivers an output power of 36dBm from an input power level of 18dBm, with a typical small-signal gain of 22dB.

Typical input and output return losses are specified as 10 and 8dB, respectively.

Fabricated using TriQuint's proven 0.25-micron pHEMT technology, the TGA4905 is housed in a carrier-plate package with overall dimensions of 13.34 x 9.65 x 1.85mm.
