Versatile GaN MMIC Low Noise Amplifiers Have Output IP3 of +32 dBm and High Input Power Handling of 5 Watts

The CMD276C4, CMD277C4 and CMD278C4 GaN MMIC LNAs deliver high linearity performance with output IP3 of +32dBm while offering high input power handling of 5W. The high input power handling feature enables system designers to avoid limiters and other protection networks, while still achieving extremely low noise figure over the operating bandwidth. These new MMIC LNAs are housed in a leadless 4x4 mm QFN package. They are ideally suited for radar and electronic warfare (EW) applications where high performance and high input power survivability are required.

The CMD276C4 is a 2.6 to 4 GHz (S Band) LNA delivering greater than 14 dB of gain with a corresponding output 1 dB compression point of +25.5 dBm and a noise figure of 1.2 dB.

The CMD277C4 is a 5 to 7 GHz (C Band) LNA with 20 dB of gain, output 1 dB compression point of +26.5 dBm and a noise figure of 1.2 dB.

The CMD278C4 is a broadband 8-12 GHz (X Band) LNA with 15 dB of gain,output 1 dB compression point of +28 dBm and a noise figure of 1.8 dB.

Two New GaAs High IP3 I/Q Mixer MMICs

We are pleased to announce that we have added two new GaAs High IP3 I/Q Mixer MMICs to our product family covering C and X-Band, the CMD257C4 and CMD258C4. These new mixers feature wide IF bandwidths and excellent image rejection, extremely compact 4x4 SMT packages and offer cost savings compared to hybrid image reject mixers and single sideband upconverter assemblies.

The CMD257C4 offers a wide IF bandwidth from DC to 3.5 GHz, and an RF LO bandwidth from 6 GHz to 10 GHz. This mixer features an excellent image rejection of 31 dB, and a low conversion loss of 5.2 dB.

The CMD258C4 also delivers an excellent image rejection of 29 dB, and a low conversion loss of 5.5 dB. This mixer RF LO range also covers C-band and X-band frequencies, from 7.5 GHz to 13 GHz, with a wide IF bandwidth of DC to 3.5 GHz.

Both the CMD257C4 and CMD258C4 can be used as either image reject mixers or single sideband upconverters, and are composed of two double balanced mixer cells and a 90 degree hybrid. An external IF hybrid is needed to complete the image rejection. These MMIC mixers come in leadless surface mount packages, and are designed to operate within specification from -40 °C to 85 °C.
