New Japan Radio Co. Ltd (NJR) has rolled out its NJG1119PB4, a bypass circuit-equipped low-noise amplifier GaAs MMIC engineered primarily for use in W-CDMA 800MHz and 2.1GHz dual-band mobile phones.

Incorporating an inverter circuit, the device has band-switching capability between 800MHz band and 2.1GHz band due to its 2bit control voltage. The new IC also offers High-gain/Low-gain mode switching capability.

With an operating voltage of 2.7V (typ.), the NJG1119PB4 features a current consumption of 2.5mA (typ.), 16dB high gain (typ.), 1.45dB low noise (typ.) and IIP3 = -3.5dBm distortion (typ.) at the 800MHz band in High-gain mode. At the 2.1GHz band in High-gain mode, it has a 2mA current consumption (typ.), 14.5dB high gain (typ.), 1.7dB low noise (typ.) and IIP3 = -3.5dBm distortion (typ.). Furthermore, in Low-gain mode, the LNA enters standby status, lowering power consumption.

Housed in FFP12-B4 packaging, the NJG1119PB4 has a sample price of $1.40 per unit.
