QPB9011
2300 - 2700 MHz 2 W Digital Control Variable Gain Amplifier
The QPB9011 is a digital variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. This amplifier module integrates gain blocks, a digital-step attenuator (DSA), and a high linearity 2 W amplifier. The module has the added feature of integrating all matching components, bias chokes and blocking capacitors. The internal 6-bit DSA provides a 31.5 dB gain control range in 0.5 dB steps, controlled with a serial periphery interface (SPITM). The module is integrated with low current amplifier shutdown capability.
The QPB9011 features variable gain from 12.5 dB to 44 dB at 2.6 GHz, +37 dBm output IP3 (at ATTN = 10dB), and +32 dBm P1dB. The module operates from a single +5V supply and is available in a compact 28-pad 6.0 x 6.0 mm leadless SMT package.
