RFMW announces design and sales support for SiTime’s SiT5358 series of MEMS Super-TCXOs. The SiT5358 series oscillators deliver ±50 ppb stability performance and can be factory-programmed to any combination of frequency (from 1 to 60 MHz), voltage and pull range. Fully compliant to the GR-1244 Stratum 3 oscillator specifications, SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology deliver stable timing in the presence of environmental stressors – airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI). Programmability enables designers to optimize the clock configuration while eliminating the long lead time and customization costs associated with quartz TCXOs where each frequency…

RFMW announces design and sales support for a 5G filter from Akoustis. The A10235 XBAW™ filter offers a small form factor and low pass band insertion loss for 5G, n78 band RF filtering applications. Center frequency is 3500 MHz with a 200 MHz bandwidth. The A10235 has a sharp cut off, achieving 30 dB of rejection within 40 MHz of the passband, and retains rejection performance beyond the second harmonic. RF power withstanding is +29 dBm making it an ideal candidate for small cell infrastructure deployments. The surface mount package measures 2 x 2.5 mm.
RFMW announces availability of the Knowles – DLI, surface mount, high frequency, directional couplers series. Part of the series, the Knowles FPC06075 spans 12 to 18 GHz and provides a 10 dB coupling factor for Ku-band applications. Passband insertion loss is only 0.5 dB maximum. Incorporating DLI’s low loss, high permittivity ceramics provides small size with minimal performance variation over temperature. These couplers offer a turnkey surface mount solution for high frequency power monitoring of incident and reflected power. The castellated surface mount package measures 2.54 x 2.032 mm.
RFMW announces design and sales support for a family of ultra-linear GaAs pHEMT 75-Ohm RF balanced amplifier ICs from Qorvo. With 5 to 1218 MHz operating bandwidth the devices feature high linearity, high gain and low noise for use as post amplifiers in optical receivers or as a low noise balanced preamps. The ICs use a 5 V supply for applications requiring lower power dissipation. Due to their wide operational bandwidth they can also be used as downstream amplifiers in DOCSIS 3.1 as well as upstream amplifiers for DOCSIS 3.1 or DOCSIS 4.0 applications. Gain ranges from 12 to 21…
RFMW announces design and sales support for a high linearity attenuator from Renesas. The Renesas F2251 Voltage Variable Attenuator (VVA) covers a broad frequency range from 50 to 6000 MHz for applications including base stations (3G, 4G, 5G), repeaters, DPD, Point-to-Point infrastructure, JTRS radios, wireless LAN and test equipment. Superb linearity is apparent with minimum 67 dBm IIP3 (typ.) and IIP2 of 105 dBm. With 33.6 dB attenuation range, insertion loss is 1.4 dB. The F2251 uses a single positive supply voltage of 3.15 to 5.25 V and features a positive attenuation slope only. Offered in a 3×3 mm VFQFPN…
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…
