RFMW announces design and sales support for a Wi-Fi diplexer from Qorvo. The QPQ2455, high-performance, high power, BAWplexer takes advantage of coexBoost technologies to deliver extremely steep skirts, simultaneously exhibiting low loss in the Wi-Fi bands and high near-in rejection to prevent interference with LTE B7/B41/B38 and B40 signals. The BAWplexer enables single antenna implementation combining both 2.4 GHz and 5-7 GHz Wi-Fi applications for simultaneous usage of Wi-Fi and LTE signals without interference. The QPQ2455 diplexer is designed for thermally challenging environment and exhibits excellent power handling capabilities.

RFMW announces design and sales support for a GaAs pHEMT/MESFET 75-ohm Push Pull amplifier. The Qorvo QPA3358 provides 34 dB of flat gain and low noise of 4 dB for DOCSIS 3.1 amplifiers and broadband CATV hybrid modules from 47 to 1218 MHz. Using a single 24V supply, the QPA3358 offers low noise and low distortion at high efficiency, consuming only 6.8 Watts of DC power in an industry standard SOT-115J package. With CSO of -70 dBc and CTB of -75 dBc, this amplifier provides 47 dBmV/ch virtual at 1.2 GHz.
RFMW announces design and sales support for APA Wireless coaxial resonator oscillators (CRO). The R2000_1SMUA6CR delivers -122 dBc/Hz typical phase noise at 10 KHz offset at its operating range of 2000 MHz. VCC is 6 Volts while the tuning voltage range is 0.5 to 4.5 V. Typical output power is 6 dBm. Packaged in a standard 0.5 x 0.5 inch castellated SMT, the API Wireless R2000_1SMUA6CR is a form/fit/function replacement for the EOL Qorvo UMX-406-D16-G.
Alternate Solutions for Worldwide TCXO Shortages The October 2020 fire at the Asahi Kasei Microsystems (AKM) factory in Nobeoka City, Japan, presented a wake-up call for the timing market and its customers. In an effort to ensure supply and mitigate risk, OEMs have qualified multiple Temperature Compensated Crystal Oscillators (TCXOs) from various suppliers. Despite these efforts, however, they have experienced an unprecedented shortage due to AKM being the single source IC manufacturer for the majority of these TCXOs. This article will identify the hardships that have been faced due to this catastrophe and explore current solutions that are available to…
RFMW announces design and sales support for an L-Band transistor from Qorvo. The QPD1029L power transistor offers 1500 Watts of RF power from 1.2 to 1.4 GHz in an air-cavity ceramic package. Internal input prematching reduces external board matching complexity and saves board space. Linear gain is 21 dB for this GaN on SiC device serving CW and Pulsed radar applications. With 75% power added efficiency, the QPD1029L operates from a 65 V drain voltage consuming 1500 mA.
RFMW announces design and sales support for a variable gain equalizer from Qorvo. The QPC7334 equalizer supports CATV amplifier and transmission systems from 5 to 700 MHz with a 20 dB slope range. Gain equalizers allow the ability to adjust for power roll off with changes such as temperature, cable length, etc. The QPC7334 has minimum insertion loss of 2.3 dB with flatness of 1 dB. Using integrated gain equalizers reduces a project’s bill of materials (BOM) and provides space reduction for dense PCB designs. Offered in a 6 x 6 mm package.
