RFMW, Ltd. announces availability of a new application note. Peregrine Semiconductor’s UltraCMOS® power limiters provide a monolithic alternative to discrete, PIN-diode limiters. They reduce design complexity by offering a drop-in solution with no external bias components. The application note is titled UltraCMOS® Power Limiter Modes and Applications and explains how Peregrine’s power limiters have two operating modes—power limiting and power reflecting. They feature adjustable P1dB threshold, high linearity performance, fast response and recovery time and superior ESD protection. Application examples include test and measurement (T&M) equipment, communication radio frequency front-end (RFFE) modules and weather radar protection.
RFMW, Ltd. announces design and sales support for a 9 – 10GHz, 35 watt, GaN power amplifier targeted towards weather and marine radar applications. The Qorvo TGA2622-SM provides a saturated output power of 45.5dBm with 18dBm input. Power added efficiency is >42% and large signal gain is 27.5dB. For non-saturated applications, small signal gain is >30dB. The TGA2622-SM requires a 28V bias capable of 290mA and comes in a 7x7mm air-cavity QFN package.
RFMW, Ltd. announces design and sales support for a B1 uplink filter. The Qorvo TQQ7301 uses BAW technology providing high isolation and low loss for small cells, LTE data cards, repeaters and base station infrastructure applications. Covering the 60MHz bandwidth of 1920 to 1980MHz, insertion loss is only 4dB while attenuation of unwanted signals is 30dB. Additionally, the TQQ7301 can handle up to 27dBm of input power. Qorvo offers this single-ended filter in an industry standard 3x3mm, SMT package.
