CMD245C4 Low Phase Noise Amplifier

6-18 GHz (C, X, Ku Band) Low Phase Noise Amplifier MMIC

The CMD245C4 is a wideband (C, X, Ku, K band) GaAs MMIC low phase noise RF / Microwave amplifier (LPNA) housed in a leadless surface mount (SMT) package that is ideally suited for military, space, and communications systems. At 10 GHz the device delivers 18 dB of gain, a saturated output power of +21 dBm and a noise figure of 4.5 dB. Also with an input signal of 10 GHz the amplifier provides low phase noise performance of -165 dBc/Hz at 10 kHz offset. The CMD245C4 MMIC is a 50 ohm matched design which eliminates the need for RF port matching.

Custom MMIC Space Qualified MIMCs
Space Qualification

Custom MMIC strives to design all our MMIC devices in a manner such that they can be readily chosen for your space applications. We offer turnkey space screening / testing service when a device is categorized as "Ready for Space Screening" on our website. In some cases, our devices have already been "Space Qualified" or "Mission Specific" and are often available from stock. Our "Mission Specific" devices are screened based on custom applications where screening is derived from MIL requirements and tailored specific to customer needs. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
