RFMW announces design and sales support for a high efficiency, DPD enabled power amplifier from Skyworks Solutions. The SKY66320-11 power amplifier features wide instantaneous bandwidth with full input/output matching, high gain and high linearity. The compact 5 x 5 mm PA is designed for FDD and TDD 4G LTE and 5G systems operating from 3600 to 3800 MHz. This 35 dB gain, 3-stage device integrated active biasing circuitry to compensate PA performance over temperature, voltage, and process variation. The SKY66320-11 is part of a high-efficiency, pin-to-pin compatible PA family supporting major 3GPP bands.

RFMW announces design and sales support for APA Wireless coaxial resonator oscillators (CRO). The R159186SMUA8CR delivers -108 dBc/Hz phase noise at 10 KHz offset over its operating range of 1590 to 1855 MHz. VCC is 8 Volts while the tuning voltage range is 1 to 12 V. Typical output power is 7 dBm. Packaged in a standard 0.5 x 0.5 inch castellated SMT, the API Wireless R159186SMUA8CR is a form/fit/function replacement for the EOL Qorvo UMX-495-D16-G.

RFMW announces design and sales support for a mmWave frequency doubler from Keysight. The HMMC-5645 multiplies input frequencies from 10 to 20 GHz to provide 20 to 40 GHz output frequencies and is usable to 50 GHz. The circuit is a full wave rectifier, using diodes and a balun. Double diode junctions are used to increase power handling with access to diode bias such that the conversion loss can be made relatively flat over about a 20 dB input power range. Available in DIE format.

RFMW announces design and sales support for a digital variable gain amplifier (DVGA) from Renesas. The F0443, dual DVGA is a highly integrated 0.6 to 2.7 GHz device designed for use in diversity/MIMO receivers. Two independent receiver paths deliver 29.5 dB typical maximum gain and 3.2 dB NF at 2.5 GHz. For each path, gain control is split into four separate digital step attenuators: DSA0 provides 6 dB of attenuation in a single step using SPI/I3C control. Its counterpart, DSA1, also provides 6 dB of attenuation in a single step but it is programmed instead using an external direct control pin. DSA2 yields 29 dB of SPI/I3C-controlled attenuation in 1 dB steps, while its counterpart, DSA3, includes 18 dB attenuation in 6 dB steps programmed via two external control pins. The device offers +39 dBm nominal output IP3 at 2.5 GHz using 372 mA total ICC for two active paths from a +5V supply voltage. The F0443 is packaged in a 7 × 7 mm, 48-LGA with 50 Ω single-ended RF input and output impedances for ease of integration into the signal path. Target applications include Multi-mode & Multi Channel Receivers, Distributed Antenna Systems and Digital Radios.

RFMW announces design and sales support for high performance power amplifier from Qorvo’s QGaN15 0.15 um GaN on SiC process. Operating from 8 to 12 GHz, the QPA2612 delivers > 12 W of saturated output power and 23 dB of large-signal gain while achieving an impressive 40% power-added efficiency. Small signal gain from this amplifier is up to 34 dB. Ideal as a final PA or to drive Qorvo GaN HPAs in Radar, communications and EW applications, the QPA2612 is packaged in a small 5 x 5 mm plastic overmold QFN. The package easily supports tight lattice spacing requirements for phased array radar applications. RF input and output ports are matched to 50 Ω and DC grounded. The device draws 250 mA from a 24 Volt supply.
