PH3135-5M

Overview

The MACOM PH3135-5M is a monolithic microwave integrated circuit (MMIC) amplifier designed for high-performance applications in the C-band frequency range. This specific model operates with a center frequency of approximately 4 GHz, providing stable gain and low noise figure characteristics suitable for communication systems. The device is housed in a surface-mount package, facilitating integration into compact RF front-end modules. Key electrical parameters include a typical small-signal gain of around 20 dB and a noise figure less than 3 dB, ensuring efficient signal amplification with minimal added noise. It requires a single positive supply voltage for operation, simplifying biasing requirements in system design.

Feature Summary

• High linearity performance for clear signal transmission
