RFMW announces a micro-site for customers and suppliers supporting solid-state RF energy technology. Magnetron tubes have dominated this market but have drawbacks with regards to degradation, reliability and power control. Solid-state RF solutions can be used to replace existing magnetron-based systems. Generally, magnetron replacement systems are made up of 1KW modules, some systems can reach 50-60 Kilowatts at their final output. Solid-state RF energy offers a number of advantages including precise power/frequency/phase and PWM control, high-speed arc detection & shutdown, stability at all power levels, no degradation of power with age, improved reliability and the use of lower voltage power…

RFMW announces Global distribution of Custom MMIC products beginning immediately. Qorvo’s recent acquisition of Custom MMIC folds their portfolio of high performance MMIC devices into an expanding list of customer solutions with Amplifiers, Control Devices, Mixers and Multipliers for next-generation long range military phased radar and Electronic Warfare (EW) systems, in addition to advanced aerospace and satellite communications and other RF/microwave signal chains through V-Band. Founded in 2006 as a fabless RF and microwave MMIC designer, Custom MMIC has been entrusted by government and defense industry OEMs with their biggest microwave circuit challenges, gaining industry recognition as one of the…
RFMW announces design and sales support for Smiths Interconnect CTX series, high frequency chip terminations. The CTX series terminations have been requalified to higher power levels and higher frequencies offering a unique combination in a 0.040 x 0.040 inch package. With Space and Defense communication systems needing higher frequency chip termination products, these devices reduce cost of ownership by supporting L through V band frequencies in a single chip. For example, the CT0404ALN2WB1 is a one Watt termination operating to 64 GHz and capable of peak power handling 10X the CW rating. Made of aluminum Nitride (AlN), the CT0404ALN2WB1 is…
RFMW announces design and sales support for a wide frequency range, ultra-low output phase noise synthesizer from Renesas. The 8V97003 spans 171.875 MHz to 18 GHz with output phase noise of -60.6 dBc at 20 kHz to 100 MHz at 6 GHz while providing high output power over its entire frequency range. The wide frequency range enables designers to use a single 8V97003 in place of multiple synthesizer modules thereby reducing both footprint and cost. Programmable output power settings deliver single-ended output power up to +13 dBm at 6 GHz, up to +10 dBm at 12 GHz, and up to…
RFMW announces design and sales support for a high power, SMT RF limiter. The RFuW Engineering model number RFLM-011015QF-290, silicon, PIN-Diode limiter module offers both high power CW and peak power protection in the 2 to 4 GHz frequency range. Capable of handling average power up to 100 Watts (50 dBm) and pulsed peak power up to 250 Watts (54 dBm at pulse width = 1 msec, duty cycle = 10%), the RFLM-011015QF-290 maintains low flat leakage to less than 14 dBm (typical), and reduces spike leakage to less than 0.5 ergs. Recovery time is <3 uSec. The combination of…
RFMW announces design and sales support for an internally matched amplifier from Qorvo. The Qorvo QPA9908 amplifier spans a frequency range of 925 to 960 MHz to support Band 3 and Band 8 small cell base stations, m-MIMO systems, booster amplifiers and repeaters with a P3dB output power of 4 Watts (36 dBm). The QPA9908 offers 32 dB of gain and is linearizable to -50dBc with 40 MHz of IBW signals. Drawing 75 mA of current from a 5 volt supply, PAE is 36% for this 5 x 5 mm, SMT packaged device which boasts on-board ESD protection.
RFMW announces design and sales support for a high frequency, GaN, power amplifier from Qorvo. The Qorvo QPA2211D offers 5 Watts of linear power at 25 dBc IMD3 with small signal gain of 26 dB. This linear power and high gain are ideal for mmWave 5G infrastructure radios operating within 27 to 31 GHz as well as Ka-Band satellite communication systems. The QPA2211D has a saturated output power of 14 Watts and is fully matched to 50 ohms with integrated DC blocking caps on both I/O ports to simplify system integration. Drawing 280 mA from a 22 V supply, this…
RFMW announces design and sales support for microwave stress relief contacts. The Anritsu S110-3 sliding contact is designed to slip over the pin of glass bead interfaces in microstrip or hybrid circuit housings. This minimizes the danger of solder connection or bond wire breakage during thermal and mechanical movement of the housing and microcircuit. The S110-3 fits 12 mil (0.38 mm), glass-feedthrough, center conductors for connection to microstrip or coplanar waveguide designs on Duroid substrates. Operational to 40 GHz, they are made of heat-treated BeCu with a bondable gold over nickel plating.
RFMW announces design and sales support for a wideband amplifier. The Qorvo TGA2962, GaN on SiC amplifier provides 10 W of saturated output power with 13 dB large signal gain from 2 to 20 GHz. With 22 % power-added efficiency at 22 V drain bias, RF ports are matched to 50 Ω and include integrated DC blocking capacitors and a RF choke. The TGA2962 is ideally suited for wideband communications systems, electronic warfare, test instrumentation, and radar applications, across both military and commercial markets where this combination of wideband power, gain and efficiency provides system designers the flexibility to improve…
RFMW announces design and sales support for an internally matched amplifier from Qorvo. The Qorvo QPA9418 spans a frequency range of 1805 to 1880 MHz with an output power 27 dBm for small cell base stations, booster amplifiers and repeaters.
