CMD245 Low Phase Noise Amplifier

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

The CMD245 is a wideband GaAs MMIC  low phase noise RF / Microwave amplifier (LPNA) ideally suited for C, X, Ku Band military, space and communications designs. At 10 GHz the device delivers 18 dB of gain, a saturated output power of +21 dBm, and a noise figure of 3 dB. With an input signal of 10 GHz the amplifier provides low phase noise performance of -165 dBc/Hz at 10 kHz offset. The CMD245 Low Phase Noise Amplifier MMIC is a 50 ohm matched design which eliminates the need for RF port matching. The CMD245 offers full passivation for increased reliability and moisture protection.

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" and are often available from stock. Just let us know when requesting price and delivery, or technical support, if your devices will be used in space.
