2-6 GHz (S, C Band) Low Noise Amplifier MMIC

The CMD228 is a broadband GaAs MMIC low noise amplifier ideally suited for S and C band microwave radios where small size and low power consumption are critical design requirments. The broadband device delivers 30 dB of gain with a corresponding output 1 dB compression point of +12 dBm and a noise figure of 1.2 dB. The CMD228 Low Noise Amplifier MMIC is a 50 ohm matched design eliminating the need for external DC blocks and RF port matching. The CMD228 also 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
