New Dual Mode 2.4 - 2.5 GHz ISM Power Amplifier
Tyco Electronics today launched the M/A-COM MAAPSS0081, a new 2.4 - 2.5 GHz ISM three-stage power amplifier specifically designed for cordless applications that require both low control voltage and high performance. With its wide voltage operating range, the MAAPSS0081 is a dual-mode power amplifier which maximizes system performance while reducing DC power consumption. "The M/A-COM MAAPSS0081 features an integrated power enabler pin providing accurate ramp control and a separate power mode pin for current savings in the lower power mode state," said David Folding, product manager, Tyco Electronics. "Additional power savings are achieved with a voltage compensation circuit, which is included specifically for applications where the amplifier supply voltage is not regulated and is directly connected to the battery. As a result the M/A-COM MAAPSS0081 is one of the most versatile and cost-effective power amplifiers available on the market today." In the High Power mode, the amplifier generates 25 dBm of output power while drawing 300 mA of current. In Low Power mode, the output power is 17 dBm with a current of 110 mA. The M/A-COM MAAPSS0081 has a typical power gain of 25 dB with an operating voltage of 2.5 to 3.0 V. The amplifier is housed in a RoHS compliant 3mm 12-lead PQFN package. Pricing and Availability The M/A-COM MAAPSS0081 is available from stock and is priced at $0.35 for quantities of 100,000.
