Mitsubishi Electronics Offers Compact, Battery-Saving GaAs FET Amplifier for PCS Band CDMA Cellular Phone Applications
Low Idle Drain Current, Low Operating Voltage and Improved Power Efficiency Add to Life of Lithium-Ion Batteries
SUNNYVALE, Calif. Mitsubishi Electronics America s Electronic Device Group today announced the North American availability of a low-voltage, low-current, high-efficiency three-stage gallium arsenide (GaAs) field effect transistor (FET) RF amplifier module for PCS Band (1.85 - 1.91 GHz) CDMA cellular phone applications. The amplifier, FA01384, features an extremely low idle drain current (Idq) of only 85 mA (typical), improved power efficiency to 37 percent, and a low 3.2-volt operating voltage that allows for 10 percent more conversation time in cellular phone applications. The module also has a compact 7.5 x 7.5 x 1.7 mm footprint.
"This new amplifier is specifically targeted to extend the battery life of CDMA cellular phones while supplying all the power and features customers have come to expect, all within a compact footprint," said Bryon Gutow, product marketing manager for microwave/RF products at Mitsubishi Electronics America. "This amplifier s power saving design saves battery life whether the cellular phone is being used or is in idle mode."
The amplifier also maintains 700 mW of output power with an excellent linearity of -29 dBc. The module is input/output matched at 50 ohms.
Packaging, Availability and Pricing
Mitsubishi s FA01384 GaAs FET RF amplifier module is available in a metal capped, glass-ceramic package. The device is now sampling and in volume production. Pricing is $7 each in 10,000-unit quantities.
