Ultra Low-Noise 2-Stage Bypass LNA
QPL9065
Product Description
The QPL9065 is a high-linearity, ultra-low noise 2-stage
gain block amplifier module with a bypass mode
functionality integrated to the second stage in the product.
At 1.95 GHz, the amplifier, under high gain mode, typically
provides 37.5 dB gain, +36 dBm OIP3, and 0.55 dB noise
figure while drawing 160 mA current from a +5 V supply.
The component also provides high performance in the low
gain mode with 17.5 dB gain, 0.55dB noise figure and +33
dBm OIP3 while drawing 70 mA current.
The QPL9065 uses a high performance E-pHEMT process.
This low noise amplifier contains an internal active bias to
maintain high performance over temperature.
The QPL9065 covers the 0.45 – 3.8 GHz frequency band
and is targeted for wireless infrastructure. The QPL9065 is
housed in a 3.5 x 3.5 mm SMT package.
