M/A-COM, a business unit of Tyco Electronics and a leading provider of wireless radio frequency (RF), microwave and millimeter-wave components, announced new low-cost two-stage driver amplifiers, the MAAMSS0072 and MAAMSS0073, extending the company’s successful family of broadband, high linearity driver amplifiers. The broad frequency range, high linearity and reliability make this M/A-COM product family ideally suited for a variety of wireless applications such as WiMax, WiBro and UMTS/WCDMA base stations.
M/A-COM’s MAAMSS0072 and MAAMSS0073 driver amplifiers are fabricated using a high reliability GaAs HBT process and achieve high third-order output intercept performance over a wide power range. The usable bandwidth for this family is extremely broad, ranging from 250 to 4000 MHz. The amplifiers can be optimized for a specific frequency range with external matching components and are housed in Pb-free, RoHS compliant 4 mm PQFN plastic packages.
These linear amplifiers are ideal for greater than 2 GHz linear applications by achieving higher gain while still maintaining linearity. The MAAMSS0072 is designed to achieve 23 dB gain, 27 dBm P1dB and 1.5% EVM with 18 dBm Pout for an OFDM signal (802.16d) at 3.5 GHz with an operating current of 235 mA. The MAAMSS0073 is geared toward even higher power by achieving 23 dB gain, 29 dBm P1dB and 1.5% EVM with 21 dBm Pout for an OFDM signal (802.16d) at 3.5 GHz with an operating current of 590 mA. Both amplifiers maintain excellent linearity over a wide dynamic range when backed off from the maximum power levels. The MAAMSS0072 and MAAMSS0073 are available from stock and are priced at $3.50 and $5.50, respectively, in quantities of 12,000.
