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 of our MMIC devices in a manner such that they can be readily chosen for your space application. We have an extensive history of successfully screening and qualifying our product to space applications per MIL-PRF-38534, MIL-PRF-38535, NASA INST standards and customer specific requirements. We collaborate with our customers to determine the appropriate screening and qualification based on their specific mission. Our space product screening and qualification are performed in-house and with approved partners. Whether you are looking for a space screened die, hermetically sealed packaged product or non-hermetic packaged product, Custom MMIC is prepared to help you address your qualification requirements
