DC to 20 GHz Wideband GaAs MMIC Distributed Power Amplifier Provides High Linearity

We have added a new packaged distributed amplifier, CMD201P5, to our growing portfolio of Broad Range Distributed Amplifier MMICs. Beyond ultra-wideband performance of DC to 20 GHz, this new distributed power amplifier also features high linearity with high output power and very low return loss.

The CMD201P5 distributed power amplifier provides 11 dB of gain with an output 1 dB compression point of over 28 dBm and output IP3 of +38 dBm at 10 GHz. The input return loss and output return loss are excellent at -16 dB and -17 dB, respectively. This GaAs amplifier also delivers excellent temperature behavior with highly stable output power, noise figure, OIP3, and P1dB over temperature.

The CMD201P5 is offered in a compact 5x5 mm plastic QFN package, and also features built 50 ohm matched design, which eliminates the need for additional RF port matching circuitry external to the MMIC.

Custom MMIC introduces Two New Broadband GaAs MMIC Mixers With Ultra Low Conversion Loss

We've added two new low loss, high linearity and high isolation MMIC mixers to our growing family of fundamental, IQ, and IRM mixers. The CMD181 and CMD261 are both general purpose double balanced mixers that can be used for upconversion and downconversion, or as image rejection mixers or single sideband modulators with the appropriate external hybrids and power splitters.

The CMD181 fundamental mixer’s RF and LO operates from 26 GHz to 45 GHz with a wide IF bandwidth of DC to 12 GHz. With a low conversion loss of -6.5 dB, the CMD181 MMIC mixer also features high LO to RF isolation of -37 dB and LO to IF isolation of -29 dB. This mixer is also highly linear, with an input IP3 of +22 dBm.

The CMD261 mixer enables frequency band translation, with an RF from 30 GHz to 46 GHz, a LO frequency range of 16 GHz to 31 GHz and an IF frequency range from 5 GHz to 20 GHz. With only -8 dB conversion loss the CMD261 MMIC mixer also features high LO to RF isolation of -30 dB and LO to IF isolation of -20 dB. These new GaAs mixers are available in compact die form and can operate reliably from -55 °C to +85 °C.
