RFMW announces design and sales support for a Southwest Antennas’ monopole whip antenna. The 1000-046 omni-directional antenna operates from 330 to 360 MHz with a peak gain of 2.0 dBi. This flexible antenna features a tough, braided aircraft wire element with a sealed heat shrink exterior and fully potted and waterproof base containing the antenna’s matching components. The resulting antenna is rugged for use in harsh environments yet is flexible enough to bend if the whip is impacted by another object. The 1000-046 features a BNC male connector for attachment.

RFMW announces design and sales support for a power limiter from Qorvo. The QPP0100 VPIN limiter provides flat leakage of 21 dBm with up to 100W peak pulsed power handling from 8 to 11.5 GHz. With exceptionally low insertion loss (1 dB) over a wide bandwidth, it requires no DC bias. Recovery time is <200 nS. The QPP0100 limiter protects receiver inputs in both commercial and military radar applications and is offered in a plastic overmolded QFN for ease of assembly.
RFMW announces design and sales support for an active beamforming RFIC from Renesas. The F6123S is a sixteen-channel, dual-beam receive active beamforming RFIC designed for application in Ku/CDL-Band (14 to 17 GHz) planar phased array antennas. The IC has eight RF input ports, two RF output ports and 16 (8 per beam) phase/amplitude control channels. The eight input ports of the F6123S may be driven by eight single-polarized elements or four dual-polarized elements of an electronically scanned array (ESA). Each channel has 6-bits of digital phase and gain control resolution spanning 360° and 26 dB of dynamic range, enabling precise…
RFMW announces design and sales support for a Skyworks Front-end Module (FEM) designed for automotive connectivity. Targeting 2400 to 2500 MHz 802.11n/ac applications in automotive infotainment and telematics, the SKYA21040 integrates a single-pole, triple-throw (SP3T) switch and low-noise amplifier (LNA) with a bypass mode in an ultra-compact package.

The SKYA21040 is provided in a small Dual Flat No-Lead(DFN) 8-pin, 1.5 x 1.5 mm package.
Most RF active devices have some sort of DC test specifications on their data sheets. This is because all semiconductor devices have a clearly defined set of operating conditions under which they are designed to function. Such parameters include: Working voltage Frequency range Power ratings Dissipation capabilities Max ratings, And more Performance specifications are mostly defined by the DC characterization of the device. Examining a DC Test Characterization Table A typical DC test characterization table from a data sheet looks similar to Figure 1 below: Figure 1: DC test characterization table The “Off Characteristics” listed in the table are acceptable…
RFMW announces design and sales support for a high gain and high linearity driver amplifier. The Qorvo QPA9122M provides 36.5 dB gain at 2.6 GHz and achieves a peak power of 27 dBm P3dB.
