RF & Wireless Skyworks Bluetooth/ Zigbee FEM RFMW announces design and sales support for a 2.4 GHz front-end module (FEM) from Skyworks Solutions. The SKY66404-11, 2.4 GHz FEM is designed for Zigbee, Thread, and Bluetooth (including Low Energy) ultra-low power IoT applications spanning sensors, beacons, smart meters and thermostats, wireless cameras, smoke and CO detectors, wearables and medical wearables. The compact (3.5 x 3.0 x 0.82 mm) multi-chip module houses circuitry providing increased efficiency, as well as 4 x greater range than stand-alone SoC devices. The module includes a power amplifier, lownoise amplifier, lowloss bypass path, transmit and receive switches, and digital controls compatible with 1.7 to 3.6 V CMOS levels. Its wide supply voltage range allows the device to be used in battery powered IoT applications over a broad spectrum of the battery discharge curve. The integrated LNA enables as much as 6 to 8 dB receive sensitivity improvement versus discrete SoCs and the low power consumption makes it ideal for operation from coin cell batteries. ■ RFMW www.rfmw.com Adjustable Current Optimizes Power Doubler Distortion Performance RFMW announced design and sales support for a GaAs pHEMT/MESFET and GaN HEMT amplifier module. The Qorvo QPA3333 Power Doubler provides 28 dB of gain for DOC- SIS 3.1 amplifiers and broadband CATV hybrid modules from 45 to 1218 MHz. Using a single 24 V supply, the QPA3333 offers excellent linearity, superior return loss and low noise which provides optimal reliability. By adjusting DC current, distortion vs. power consumption can be optimized over a wide range of output levels. Offered in an 11 x 8.5 mm package. ■ RFMW www.rfmw.com Always-on Power Limiter RFMW announced design and sales support for a highpower, SMT RF limiter. The RFuW Engineering model RFLM- 102402QF-290, silicon, PIN- Diode limiter module offers both high power CW and peak power protection in the L & S-Band region (1 to 4 GHz). Capable of handling average power up to 100 W (50 dBm) and pulsed peak power up to 1000 W (60 dBm at pulse width = 25 µs, duty cycle = 5 %), the RFLM-102402QF-290 maintains low flat leakage to less than 14 dBm (typical), and reduces spike leakage to less than 0.5 ergs. Recovery time is
