NXP’s BGU703x and BGU704x low-noise amplifiers (LNAs)

upgrade overall picture quality with improved signal handling

(NF, dynamic range), while reducing the number of external

components.

Produced in NXP’s own QUBiC4+ Si BiCMOS process, they

improve signal handling by compensating for the signal loss at

the tuner switch. This can improve system performance by as

much as 7 to 10 dB.

The BGU7031, BGU7041, and BGU7044 are LNAs with fixed gain.

The BGU7032, BGU7042, and BGU7045 have an additional

bypass mode, and the BGU7033 adds two gain levels along

with the bypass mode. In bypass mode, the devices consume

less than 5 mA of current. Integrated biasing and 75 Ω

matching reduces footprint by eliminating as many as 15

components compared to discrete solutions.

All the devices can be used with discrete or Si can tuners, as

well as with on-board tuners. They deliver more robust ESD

performance compared to GaAs solutions, withstanding >2 kV

human body model (HBM) and >1.5 kV charged device model

(CDM).

(BGU704x)

Applications

 Terrestrial and cable set-top boxes (STBs)

 Silicon and can tuners

 Personal and digital video recorders (PVRs and DVRs)

 Home networking and in-house signal distribution

NXP LNAs BGU703x &BGU704x for TVs/STBs

Designed for high linearity and low noise, these 3.3 and 5 V wideband LNAs support multi-tuner applications

in TVs, DVR/PVRs, and STBs operating between 40 MHz and 1 GHZ. A unique programmable gain with

bypass mode compensates for tuner switch signal loss (important in multi-tuner systems), and improves

overall system performance by 7 to 10 dB.
