Notch Filter Bank
AM3129 is a miniature voltage-tunable notch filter bank covering the 1 to 6 GHz frequency range in a 9 mm QFN package. Six notch filters and two bypass paths with SP8T switches on the input and output are contained in the multichip module. Separate tune voltages provide precise control of center frequency and notch bandwidth. AM3129 provides an excellent filtering solution for receivers or transceivers requiring flexible frequency rejection, high dynamic range, low insertion loss, small size, weight and power consumption.

Fixed Waveguide Attenuators
Eravant is introducing a new line of precision fixed waveguide attenuators. They are manufactured with wire EDM to ensure high accuracy and a smooth internal finish. The attenuators feature anti-cocking flanges to reduce misalignment errors and sandblasting treatment to provide a durable, aesthetically appealing outer finish. WR-15 through WR-10 models are in stock right now. Other models (WR-42 through WR-06) are in development and scheduled to be released throughout the rest of the year.
RF Hybrid Couplers
Fairview Microwave Inc., an Infinite Electronics brand and a leading provider of on-demand RF, microwave and mmWave components, has extended its RF hybrid coupler product line with new models to meet high frequency component demands. These high performance hybrid couplers are ideal for RF applications requiring an equal split of input and output ports with 90-degree or 180-degree phase shifts while maintaining high isolation between ports. Fairview’s 21 new RF hybrid coupler models feature a coaxial design with SMA and 2.92 mm connectors.

Ultra-Broadband Bias Tees
HYPERLABS Inc. has developed a line of ultra-broadband bias tees with bandwidths extending from 35 kHz to over 67 GHz that can be used to apply or monitor a DC voltage on high speed data or RF signaling. Model number HL9447 has a maximum insertion loss of 1.25 dB and offers a 175 mA current rating on the DC port. The HL9547 is a higher power offering with a current rating of 1000 mA and a typical 2.0 dB insertion loss.
26 to 34 GHz, 20 dB Directional Couplers
MECA expanded offering of 5G mmWave products. Featuring 10 dB couplers covering 26 to 34 GHz with 2.92 mm interfaces. Typical specifications of 1.5:1 VSWR, 15 dB directivity, 1 dB insertion loss and .4 dB frequency sensitivity. Also available are attenuators, terminations, bias tee’s, DC blocks and adapters. Additionally, octave and mulit-octave models covering up to 50 GHz built by J-Standard certified assemblers and technicians. Made in U.S. and 36-month warranty.
Digitally Controlled Analog Phase Shifter
Model number PS-12-360-QQ1470 Option 107 is a 1.7 GHz, digitally controlled analog phase shifter with capability for phase shifting from 0 to 360 degrees. The unit consists of an analog phase shifter and a digital-to-analog converter. Eight logic input lines allow 256 discrete values of phase. This particular unit operates at 1.7 GHz with 360-degree minimum phase shift. An eight-bit digital control sets the phase with 1.41-degree resolution and switching time is 200 nS. Insertion loss is typically 4 dB and worst case insertion loss is 6 dB.

Low ESR Capacitor Assemblies
RFMW announced design and sales support for Knowles - Novacap SV Series capacitor assemblies. SV series capacitors offer high capacitance-to-volume ratio, low equivalent series resistance and low equivalent series inductance while reducing overall circuit board footprint. Vertical stacking of ceramic capacitors provides far superior performance than either aluminum or tantalum electrolytic capacitors. Up to ten, same size chips, may be stacked with various lead configurations to safeguard against thermal and mechanical stresses as with the SV2220BB476M101LNW-10R, 47uF 100V (VDCW) assembly.
5G Dual-Channel Receiver Front Ends
Richardson RFPD, an Arrow Electronics company, announced the availability and full design support capabilities for a family of RF and mmWave front-end modules from Analog Devices Inc. These dual-channel receiver front-end multichip modules are designed for time division duplexing applications that operate from 2.4 to 4.2 GHz (ADRF5545A), 3.7 to 5.3 GHz (ADRF5547) and 1.8 to 2.8 GHz (ADRF5549). The devices are configured in dual channels with a cascading two-stage LNA and a high-power silicon SPDT switch.
