CMD247 Low Phase Noise Amplifier

30-40 GHz (Ka, Q, U Band) Low Phase Noise Amplifier MMIC

The CMD247 is a wideband (Ka, Q, U band) GaAs MMIC low phase noise RF / Microwave amplifier (LPNA) ideally suited for military, space and communications systems. At 35 GHz the amplifier MMIC delivers 13 dB of gain, a saturated output power of +15 dBm and a noise figure of 5 dB. Also, the amplifier provides low phase noise of less then -160 dBc/Hz at 10 kHz offset. The CMD247 MMIC is a 50 ohm matched design which eliminates the need for external DC blocks and RF port matching. The CMD247 also 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.
