Tyco Electronics has released a new family of M/A-COM driver amplifiers for point-to-point (P2P) radios. The new driver amplifier family covers allocated point-to-point bands from 4.9 GHz to 15.4 GHz. While MAAM-007523 amplifier covers a band of 4.9 GHz to 8.5 GHz, MAAM-007524 is designed for 10.0 GHz to 15.4 GHz. The amplifiers feature +32 dBm third-order intercept point (IP3) linearity and P1dB levels ranging from 19 to 21 dBm. They are self-biased and may be operated with drain supplies ranging from 4.5 to 8.0 V to optimize system performance including linearity, gain and power efficiency. This new family of driver amplifiers complements the existing line of M/A-COM point-to-point amplifiers and work well together to provide excellent system performance.

According to Tyco Electronics, the large frequency range supported by these amplifiers, as well as their typical gain flatness across individual P2P bands being ±0.5 dB, makes these amplifiers suitable for end-to-end P2P communications.

All dies are fabricated using M/A-COM’s multi-function self-aligned gate (MSAG) process, which features a rugged polyimide coating and no air bridges. This coating produces a rugged chip for high assembly yields. The mean time to failure (MTTF) is one million hours at 170 ºC junction temperature and the package option is a 16-lead, 4 mm PQFN package, which is suitable for standard surface-mount assembly processes. Each amplifier part is available in bare die and plastic packaged options. The amplifiers are RoHS-compliant and compatible with a 260ºC reflow temperature.

The MAAM-007523 and MAAM-007524 driver amplifiers are both available from stock in either bare die or plastic package options, and are priced at $16 each in quantities of 1000. Production lead times start at 12 weeks for bare die and 16 weeks for plastic packaged options.
