CMD171P4 Power Amplfier

9.5-11 GHz (X Band) Driver Amplifier MMIC

The CMD171P4 is an RF / Microwave GaAs MMIC driver amplifier housed in a leadless 4x4 mm plastic surface mount (SMT) package. The CMD171P4 is ideally suited for complex communications systems where small size and high linearity are crucial design requirements. At 10 GHz the amplifier delivers 21 dB of gain with a corresponding output 1 dB compression point of greater than +28 dBm. The CMD171P4 is a 50 ohm matched design which eliminates the need for external DC blocks and RF port matching. The CMD171P4 is also equipped with an on-chip detector for applications where power leveling is required.

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.
