RFMW announces the addition of a new Business Development Manager for the Americas specializing in RF Power applications support. Leonard Pelletier is a high energy, creative engineering expert on RF power amplifier design and RF component applications. Mr. Pelletier’s substantial background comes from his experience working for a major RF power semiconductor manufacturer that specializes in LDMOS, GaN and SiGe device technologies where he worked in both design and technical support functions. Author, manager, trainer and public speaker, Mr. Pelletier was personally instrumental in the transition from bipolar devices to the use of LDMOS technology by cellular infrastructure OEMs over…
RFMW announces design and sales support for high-performance, mmWave, 5G front end modules from Qorvo. The QPF4010 MMIC mmWave FEM operates from 24.25 to 27.5 GHz with integrated LNA+TR SW+PA. The receive path (LNA+TR SW) is designed to provide 13.5 dB of gain and a typical noise figure of 4.0 dB. The transmit path (PA+SW) provides 17 dB of small signal gain and a saturated output power of 22.5 dBm. Supporting 5G-n258 phased array base stations and terminals, the frequency coverage and operational flexibility allow support of satellite communications, point-to-point data links and 5G repeaters. Average Tx power is 14…
RFMW announces design and sales support for a family of high efficiency, DPD enabled power amplifier from Skyworks Solutions. These power amplifiers are designed for the stringent requirements of enterprise small cell radios and offer wide instantaneous bandwidth, with high gain, and are fully input/output matched. Wide bandwidth enables higher data rates for newer 5G systems. Active biasing circuitry is integrated to compensate for PA performance over temperature, voltage, and process variations. Housed in compact 5 x 5 mm packages, the SKY663xx-11 family of PAs is ideal for 5G systems operating from 2.3 to 5 GHz.
RFMW announces design and sales support for an S-Band transistor from Qorvo. The QPD1881L power transistor offers 400W of RF power from 2.7 to 2.9 GHz in an air-cavity package. With 75% power added efficiency, the QPD1881L runs from a 50 V consuming 700 mA. L3 gain 18 dB. The RF input is prematched for civilian and military radar applications supporting both CW and pulsed operation.
RFMW announces design and sales support for an integrated, dual-path RF Switch / LNA. Each path of the Renesas F0452B consists of an RF switch and two gain stages with 6 dB of gain control supporting analog front-end receivers in Active Antenna System (AAS) from 2300 to 2700 MHz. The F0452B provides 34 dB gain with +23 dBm OIP3, +15 dBm output P1dB, and 1.5 dB noise figure at 2600 MHz. Gain is reduced 6 dB in a single step with a maximum settling time of 31 ns. The device uses a single 3.3 V supply and 130 mA of…
RFMW announces design and sales support for a full band Citizens Broadband Radio Service (CBRS) filter designed for the US market. The Sangshin MBP84RC2N3625S150D is a small form factor ceramic filter covering the full 3550 to 3700 MHz CBRS radio band. Rated to 5 Watts average power, it offers excellent properties in terms of size vs performance making it suitable for high power MIMO applications. Low passband insertion loss of 2 dB max. and 1 dB of typical pass band ripple helps maintain maximum power and throughput over an operating temperature of -40 to +85 degrees C. Measuring just…
RFMW announces design and sales support for a MEMS-based, digitally controlled OCXO platform. SiTime’s Si5721 digitally controlled OCXO offer’s ±5 to ±8 ppb stability at frequencies from 1 to 60 MHz. These devices can be used to replace legacy quartz VCOCXOs in emerging 5G and IEEE 1588 synchronization applications while improving overall system performance and robustness with 10 times better dynamic stability (150 ppt/°C ΔF/ΔT), resistant to airflow and thermal shock. I2C digital frequency tuning eliminates board noise and no mechanical shields are needed. Combined with a 9 x 7 mm footprint, the Si5721 offers unmatched ease-of-use and eliminates restrictions…
RFMW announces design and sales support for a high performance pHEMT MMIC amplifier. With high gain, high linearity, and low distortion from 50 – 1800 MHz the Qorvo QPL1812 amplifier is ideal for broadband cable applications. An integrated active bias circuit provides stable gain over temperature and process variations.. The QPL1812 delivers 19 dB of gain for DOCSIS 4.0 amplifiers, nodes and CATV CPE equipment. Designed to run from a single 8V supply, without the need for an external dropping resistor, this single ended amplifier is available in a SOT-89 package.
RFMW announces design and sales support for MECA Electronics broadband power divider/combiners. The 802-2-4.250 RF power divider/combiner offers 2-way, in-phase performance from 0.5 to 8 GHz. Capable of handling up to 30 Watts of average power with an operating temperature of -55 to +85 degrees C, it offers phase and amplitude balance generally seen only in narrow band models. Typical insertion loss is 0.8 dB with 22 dB isolation. Available in 4-way and 8-way versions as 804-2-4.250 and 808-2-4.250 respectively, the broad band nature of these power divider/combiners eliminates the need to increase the component count in D.A.S systems.
