GaAs Sub-GHz Linear Power Amplifier Eases UHF System Development
CML Micro extended its SµRF range of sub-GHz MMICs with a 2-W power amplifier. Optimized for linear performance and high reliability, the CMX90A006 can be used as a final-stage ISM (915 MHz) and SRD (868 MHz) band power amplifier in wireless transmitter applications. Delivering +33-dBm output power at 1-dB gain compression over the 860- to 930-MHz frequency range, the two-stage indium gallium phosphide (InGaP) devices are suitable for multi-market applications operating in the license-free bands. Operated from a 2.5- to 5.25-V supply voltage, the CMX90A006 enables system-level optimization using a single-cell lithium battery for portable applications.
Fabricated with advanced InGaP HBT process technology, the device attains 52 % PAE, 33 dB of small signal gain and +42-dBm output third order intercept (OIP3) at 26 dBm per tone. Housed in a 4- x 4-mm thermally enhanced VQFN package for space-constrained designs , the RF input port of the device is internally matched to 50 Ω to reduce component count. The EV90A006 evaluation board has an output matching network to optimize performance for a given application.
