CMX90G302 1.4 – 7.1GHz Positive Gain-Slope Amplifier +2dB www.cmlmicro.com Page 1 D/90G302/3 September 2022
Description
The CMX90G302 is a low-power 50 Ω cascadable MMIC gain block suitable for a wide variety of wireless applications operating in the 1.4 – 7.1 GHz frequency range. The gain block has a positive gain-slope of + 2dB across the band, eliminating the need for equalisation and compensates for increasing system losses with frequency. CMX90G302 is highly integrated for ease of use, minimising component count and board area. RF ports are matched on -chip to 50 Ω with DC - blocking capacitors. An active bias circuit allows the device to operate over a wide supply voltage of 2.7V to 5V with typical current of 20 mA. Using GaAs pHEMT to provide a combination of low DC power, low noise and high gain. An a lternative part , CMX90G301, is available for applications that require less gain-slope compensation.
Applications
- Tx and Rx systems
- 4G / 5G wireless infrastructure
- TDD and FDD
- IF amplifier
- License-free bands
- General purpose gain block
- Eliminate passive equaliser
