Pasternack introduces a line of voltage variable attenuators offering up to 60 dB of attenuation across broad frequencies from 400 MHz to 18 GHz. This line of voltage variable attenuators is most commonly deployed in applications such as electronic warfare, instrumentation, point-to-point and point-to-multipoint radios, fiber optic and broadband telecom, microwave radio and VSAT, military radios, radar, ECM, SATCOM and sensors, and R&D.

Models SWF-65302350-15-B1, SWF-61302350-15-B1, SWF-63302350-15-B1 and SWF-58302350-15-B1 are V band, waveguide bandpass filters designed for WiGig applications. All four filters offer a 2 GHz passband with 50 dB typical rejection. The filters also have a nominal insertion loss of 2.5 dB. Since both low and high end cut off frequencies can be selected by modifying the design, custom models are available.
RFMW Ltd. announces design and sales support for a small cell duplexer. The Qorvo TQQ6103 BAW technology offers high isolation for LTE Band 3 uplink (1747.5 MHz) and down link (1842.5 MHz) filter requirements in base stations, repeaters, signal boosters and small cells. With full 75 MHz bandwidth, in band insertion loss is only 4.1 dB while UL/DL attenuation is 44 dB. The TQQ6103 requires no external matching and handles 29 dBm of power.
MECA is excited to announce our family of 5 G ready millimeter-wave couplers, isolators covering C to V bands. Ideal for Satcom, 5 G and backhaul upgrade applications. Available in 10 and 20 dB models covering 6 to 40 GHz with 2.92 mm connectors.
MECA is pleased to announce its latest addition to our extensive line of stripline couplers with the 785-dB to 9.700, covering from 7.0 to 12.4 GHz. Available in 10 and 20 dB models with SMA female connectors, optimized for excellent performance with industry leading specifications offering typical VSWR’s ranging from 1.30:1, Isolation of 20 dB typical.
RFMW Ltd. announces design and sales support for the RF circulator isolator, (RFCI) model RFCR8801 circulator. The RFCR8801 covers the full S-band (2-4GHz) in a drop-in package configuration. Broadband performance is outstanding with typical insertion loss <0.5 dB and >19 dB isolation. Forward power handling is rated at 50 W average and 500 W peak. Reverse power handling is 30 W CW.
Pasternack debuts lines of waveguide bends operating from 5.85 to 90 GHz across 12 frequency bands (from C band to W band). These waveguide bends are commonly used in applications such as instrumentation, test benches, high efficiency RF, microwave and mm-wave transmissions, SATCOM, MILCOM, radar and telecom. Pasternack’s in-stock and ready-to-ship waveguide bends boast low loss and VSWR as low as 1.08:1.
Richardson RFPD Inc. announced the availability and full design support capabilities for a new UltraCMOS® digital step attenuator (DSA) from Peregrine Semiconductor Corporation. The PE4314 is a 75Ω HaRP™ technology-enhanced, 6-bit RF DSA that operates from 1 MHz to 2.5 GHz and features glitch-less attenuation state transitions and low distortion. It supports 1.8 V control voltage and an extended operating temperature range up to +105° C.
RFMW Ltd. announces design and sales support for the Qorvo 885075 BAW filter featuring LowDrift technology. LowDrift BAW filters have dramatically reduced temperature sensitivity resulting in improved insertion loss, longer battery life, and fewer service interruptions in final designs. The Qorvo 885075 is highly selective for B40 applications from 2300 to 2400 MHz and offers excellent W-Fi rejection. Insertion loss is 3 dB and Wi-Fi attenuation is specified at 34 dB.
Vaunix Technology Corp., a manufacturer of USB controlled and powered test equipment, recently added a programmable digital attenuator to their LDA family of PC-driven Lab Bricks, the LDA-602EH. The LDA-602EH has a large attenuation range of 120 dB with an exceptional 0.1 dB step size, allowing for both precision and accuracy during fading tests or device characterizations. This attenuator also features a fast 15 µs switching speed.
