MMIC Amplifiers Offer High Output Power and Positive Bias

Custom MMIC has added three new GaAs MMIC power amplifiers covering 5 to 11 GHz to our growing standard product library. The CMD169P4 (5 – 7 GHz), CMD170P4 (7.5 – 9 GHz) and CMD171P4 (9.5 – 11 GHz) each have an output 1 dB compression point of greater than +28 dBm, with gain levels from 20 to 30 dB. All three designs require only positive bias, thereby eliminating the need for costly and complicated sequencing circuitry. They also offer an on-chip detector for applications where power leveling is required. The amplifiers are housed in Pb-free RoHs compliant 4x4 QFN plastic packages and are 50-ohm matched on the input and output ports. DC blocks are not required.

20 GHz Distributed Amplifier MMIC Offers Positive Bias

The CMD173 is a wideband GaAs MMIC distributed amplifier die for applications from DC to 20 GHz. This device delivers greater than 15 dB of gain with a corresponding output 1 dB compression point of +18 dBm, and a noise figure of 1.5 dB at 8 GHz. The CMD173 is an all-positive bias design, thus eliminating complicated and costly sequencing circuits while also simplifying board layout. In addition, the use of on-chip tracking circuits delivers consistent performance over temperature and process variation. The CMD173 is a 50 Ohm matched design that offers full passivation for increased reliability and moisture protection. The device does require off-chip bias networks, which is typical of this amplifier topology. The CMD173 is suitable for microwave radio and VSAT, telecom infrastructure, test instrumentation, and military and space applications.
