Custom MMIC Launches GaAs MMIC Switches Featuring Binary Decoder Circuitry

Press Release Summary:

Custom MMIC’s GaAs MMIC Switches are available in CMD235C4 and CMD236C4 models with range a of DC-18 GHz and insertion loss of 2.5dB. Units are housed in 4 x 4 mm QFN surface mount package and are operated on 0/-5V. CMD236C4 switch is suitable for military and instrumentation applications and features an isolation of 42 dB at 10 GHz whereas CMD235C4 with isolation of 40dB at 10 GHz. These GaAs MMIC Switches offer an input P1dB of 21 dBm and a switching speed of approximately 60 ns.

Original Press Release:

New Broadband Non-Reflective GaAs MMIC Switches Cover Frequency of DC-18 GHz

Chelmsford, MA – April 16, 2018 – Custom MMIC, a leading developer of performance driven monolithic microwave integrated circuits (MMICs), continues to rapidly add to its extensive family of MMIC Switches; with two new GaAs MMIC switches, the non-reflective CMD235C4 and CMD236C4

The CMD235C4 is a DC-18 GHz broadband MMIC SP5T switch offering broadband performance with an insertion loss of 2.5dB and high port-to-port isolation of 40dB at 10 GHz.

The CMD236C4 covers DC to 18 GHz and offers a low insertion loss of 2.5 dB and high isolation of 42 dB at 10 GHz. Ideally suited for high performance military and instrumentation applications, both switches provide a switching speed of approximately 60 ns and an input P1dB of 21 dBm. 

These switches feature binary decoder circuitry that reduces the number of logic control lines. The control voltages for both switches are 0/-5V. Both MMICs are housed in a ROHS compliant 4x4 mm QFN surface mount package.
