QBH-9076 Amplifier
FEATURES • 800-960 MHz • 2.5 dB typical noise figure is ideal for a second stage in a high dynamic receiver • +50 dBm typical third order intercept is ideal for a base station PA driver • Remarkably stable over temperature
The QBH-9076 is designed for the 800 MHz to 960 MHz frequency range. The unit uses miniature hybrid couplers on the input and output to combine the performance of a pair of cascode GaAs FET amplifiers and to maintain excellent input and output VSWR.
• Low VSWR PACKAGING • Die heat spreaders are directly attached to the copper heat spreader for maximum heat dissipation • Efficient thermal design
