RFMW Ltd. announces design and sales support for a DOCSIS 3.1 compliant return path amplifier. The Qorvo QPB3321 is an HBT, single-ended, RF amplifier IC operating from 5 to 210 MHz. Designed to provide a low noise, high gain option, it uses an 8 V power supply to provide lower overall power dissipation.

RFMW Ltd. announces design and sales support for an integrated Edge QAM amplifier module from Qorvo. The RFAM3620 employs GaAs pHEMT die, GaAs MESFET die, a 20 dB range variable attenuator and a power enable feature.

RFMW Ltd. announces design and sales support for a 75 ohm digital step attenuator (DSA). The Qorvo QPC3614 offers 6-bits of attenuation with 0.5 dB LSB step size providing 31.5 dB of attenuation range from 5 to 1500 MHz.

RFMW Ltd. announces design and sales support for XMA Corp’s 8582-6150-xx series of 2.4 mm, 50 GHz attenuators. The XMA coaxial attenuators are available in standard dB values of 3, 6, 10, 20 and 30 dB.

RFMW Ltd.'s QPC9314 PIN-diode based switch can handle 52 W of average power with an LTE signal (8 dB PAR) and contains two LNA stages, and a 1-bit DSA to provide a high and low gain mode.

RFMW Ltd. announces design and sales support for an integrated front end module (iFEM) designed for Wi-Fi applications. Qorvo’s QPF7200 integrates a 2.4 GHz power amplifier, bypassable transmit BAW filter, LNA with bypass function and receive coexistence BAW filter into a single module.

RFMW Ltd. announces design and sales support for an ultra low-noise amplifier with integrated bypass function. The Qorvo QPL9095 offers 0.6 dB noise figure and operates from 500 to 1000 MHz with 22 dB of gain.

RFMW Ltd. announces support for dipole antennas with integrated internal bandpass filtering. The Southwest Antennas’ 1001-139 includes a 3-pole, bandpass filter to reduce interference from co-located radios operating outside the antenna’s 2.1 to 2.5 GHz operational frequency range.

RFMW Ltd. announces design and sales support for Smiths Interconnect “Outrigger” resistors. The CRH04091005F is a 100 ohm resistor capable of handling 1 W CW and up to 10 W of pulsed RF power yet measures only 1.02 x 2.29 mm. 

RFMW Ltd. announces support for a balanced amplifier module with embedded hybrid couplers. The Qorvo QPA9807 offers single ended input and output ports with very good return loss and incorporates and enable pin to shut down the amplifier for improved receive sensitivity.
