BGU7042
1 GHz wideband low-noise amplifier with bypass
Rev. 2 — 13 September 2011
Product data sheet
1. Product profile
1.1 General description
The BGU7042 MMIC is a 3.3 V wideband amplifier with bypass mode. It is designed
specifically for high linearity, low-noise applications over a frequency range of 40 MHz to
1 GHz. It is especially suited for Set-Top Box applications.
The LNA is housed in a 6-pin SOT363 plastic SMD package.
1.2 Features and benefits
Voltage supply of 3.3 V
Internally biased
Programmable between Gp = 10 dB and bypass
Flat gain between 40 MHz and 1 GHz
Noise figure of 3.8 dB
High linearity with an IP3O of 29 dBm
75 input and output impedance
Power-down during bypass mode
Bypass mode current consumption < 5 mA
ESD protection > 2 kV Human Body Model (HBM) and >1.5 kV Charged Device Model
(CDM) on all pins
1.3 Applications
Terrestrial and cable Set-Top Boxes (STB)
Silicon and “Can” tuners
Personal and Digital Video Recorders (PVR and DVR)
Home networking and in-house signal distribution
