Analog high linearity low noise variable gain amplifier
Rev. 1 — 10 August 2012
Preliminary data sheet
1. Product profile
1.1 General description
The BGU7062 is a fully integrated analog-controlled variable gain amplifier module. Its
low noise and high linearity performance makes it ideal for sensitive receivers in cellular
base station applications. The BGU7062 is operating in the 1710 MHz to 1785 MHz
frequency range and has a gain control range of 35 dB. At maximum gain the noise figure
is 0.85 dB. The gain is analog-controlled having maximum gain at 0 V and minimum gain
at 3.3 V. The LNA can be bypassed extending the dynamic range. The BGU7062 is
internally matched to 50 ohm, meaning no external matching is required, enabling ease of
use. It is housed in a 16 pins 8 mm 8 mm 1.3 mm leadless HLQFN16R package
SOT1301.
