Mimix 2.1-2.5 GHz InGaP HBT Matched Gain Block Amplifier

The CGB7389-SC is a single stage, high power, high dynamic range, utility gain block amplifier. Designed for applications operating within the 2.1 to 2.5 GHz frequency
range, Mimix’s broadband, cascadable, gain block amplifier is an ideal solution for transmit, receive and IF applications.
This MMIC amplifier is available in an industry standard SOT-89 package. Mimixs InGaP HBT technology and an industry low thermal resistance offers a thermally robust
and reliable gain block solution.

The InGaP HBT die have extra pads to enable thorough DC testing. This unique test capability and the inclusion of ESD protection on all die, significantly enhances the quality, reliability and ruggedness of these products.
This gain block amplifier offers significant ease of use in a broad range of applications. The combination of high gain, P1dB and high OIP3 at low current makes the
CGB7389-SC an ideal transmit and receive solution when used in applications including 3G, fixed wireless broadband, WLAN and WiMAX services operating from 2.1 to 2.5 GHz.
