IRVINE, Calif. -- Toshiba America Electronic Components Inc. here has developed its first RF hetero-bipolar transistor (HBT) microwave monolithic power amplifier in gallium arsenide, the company said today.
Toshiba's new power amplifier, the TG2013F is Toshiba's first GaAs HBT device to be marketed in the United States.
The company said the new GaAs HBT power amplifier is ideal for applications in 1.9-GHz personal communications systems (PCS) and code-division multiple access (CDMA) systems. The new device offers high output power of 29 dB/mW, a single power supply of 3.6 volts, high gain of 24 dB, efficiency to 30% and low voltage standing wave ratio (VSWR) of less than 3. With a low VSWR, the device transmits more power rather than reflecting it, therefore making it more efficient.
Offering a GaAs HBT power amplifier with bias circuit, the TG2013F provides better linearity than a silicon device. While the high output power and high gain boosts the signal for transmission, the small 5.3 --by-6.4-mm package enables engineers to create smaller design solutions.
Toshiba's GaAs HBT features an internal gain control amplifier, which prevents the final stage of the power amplifier from going into overdrive. In addition, Toshiba's proprietary temperature compensation circuit prevents the final stage of the power amplifier from breaking down due to overheating.
"Our customers have requested a GaAs-based power amplifier solution for high gain and low power consumption applications," said Brach Cox, business development manager for Toshiba's RF Business Unit. "The TG2013F represents Toshiba's first GaAs HBT power amplifier to be added to our RF family of products."
With the TG2013F RF power amplifier's internal gain control amplifier and temperature compensation, Toshiba is able to lower system and manufacturing costs by simplifying the design process and reducing the number of parts, he said.
The TG2013F is housed in a 20-pin high-power small-outline package (HSOP) type packaging. Samples will be available next month, priced at $4.50 each in 1,000 piece quantities. Full production quantities will be available in the second quarter, and production pricing will beavailable at that time.
