Last week, the team at CEL told me that they were now supplying NEC's new uPD5740T6N low noise amplifier (LNA). This is a wideband IC with a bypass/through function, and it is designed to be a part of the receive chain in broadcast TV applications on mobile phones, smart phones, and other hand held devices.

As with all components in a handheld, the new LNA had to be designed for low voltage, low current consumption, and small size. The LNA switches from amplification mode when receive signals are weak to bypass mode when receive signals are strong. CEL reports that the new LNA is now standard on several of Newport Media’s mobile TV reference designs.

Anyway, here are the key specs:

Frequency: 0.05 to 1 GHz
Supply Voltage: 2.8 V
Control Voltage: 1.0 V
LNA Mode at 770 MHz: Icc = 5mA, NF=1.5 dB, Gp=13.5 dB, IIP3 = +2 dBm
Bypass Mode at 770 MHz: Icc = 1uA, Insertion Loss = 1.3 dB, IIP3 = + 30 dBm
Package: 6pin TSON, 1.5 x 1.5 x 0.37 mm

Alternative apps include short range wireless systems in the 450 MHz, 868 MHz and 900 MHz frequency ranges, including smart meters, smart grid, and wireless security. The device is shipping now and is priced at $0.48 in quantities of 100,000. Evaluation boards are available.
