Low noise amplifier helps optimise receiver performance
Freescale has introduced a new enhancement mode pHEMT low noise amplifier.
The MML09231H is based on GaAs process technology and designed to optimise receiver performance for a range of wireless systems operating between 700 and 1400MHz.
The device has a noise figure of 0.36dB at 900MHz, can tolerate a maximum input signal of 20dBm and has an rf output peak power of 24.5dBm.
It also offers a high reverse isolation of -21dB, small signal gain of 17.2dB and current consumption of only 55mA from a single 5Vdc supply.
Features include a power-down pin, active bias control for maintaining constant current, unconditional stability over temperature, and low external component count.
