High Frequency Couplers
Pasternack, an Infinite Electronics brand, has launched a new series of high frequency couplers that are ideal for 5G telecommunication, automotive radars, SATCOM, point-to-point radios and aerospace applications. Pasternack’s new line of high frequency RF directional couplers consists of 24 models that have a high max operating frequency range from 26.5 to 67 GHz. These new couplers deliver excellent isolation, low insertion loss and very good return loss.
Tunable Bandpass Filters
Pole/Zero has released their next generation line of NANO-POLE® tunable bandpass filters. Features include +30 dBm in-band power handling: for BW 3 dB filters ≥ 7percent, +27 dBm for 5 percent filters. ND +23 dBm for 3 percent filters. +42 dBm IIP3 typical, 10 μs typical tune time. 15 dBc typical selectivity at fc ± 10 percent: 5 percent, 3 percent filters provide more selectivity; yet have higher insertion loss. For optimum filter performance, 1.5:1 tuning ratios are recommended.
PMI Model No. DTA-1G18G-60-7-CD-1-HERM is a non-reflective 7 bit programmable 60 dB pin diode attenuator with a step resolution of 0.5 dB over the frequency range of 1 to 18 GHz. This model is in a hermetically sealed package. It has a max insertion loss of 5 dB and a max VSWR of 2:1. This unit is outfitted with SMA female connectors and a 15-pin Micro-D female connector in a hermetically sealed housing measuring 2 x 2.79 x 0.66 in.

RF Bandpass Filters
PolyPhaser has expanded its RRF series of bandpass filters engineered to function between 219.5 to 222 MHz frequencies for positive train control (PTC) communications. The new RRF-ITC-219-NFF filter reduces interference issues by blocking unwanted signals due to co-location. The filter also incorporates > 60 dB of attenuation at 88 to 108, 160 to 162, 210 to 216 and 452 to 458 MHz.
Miniature SPDT Switch
RLC Electronics introduced an addition to their miniature SPDT switch product line. This switch is offered in a unique package with connectors in a “T” configuration for ease of connection/mating at the system level, and is a perfect drop-in replacement for pin diode switches. The switch is offered in both surface mount and connectorized versions and operates from DC to 18 GHz. Standard options are available include Indicators and TTL Drivers. The switch measures 1 x 1 x 0.9 in.
RLC Electronics Inc.
Model STF-34-S1 is a full band Faraday isolator that operates from 22 to 33 GHz. The Faraday isolator is constructed with a longitudinal, magnetized ferrite rod that causes a Faraday rotation of the incoming RF signal. The Faraday isolator offers 28 dB typical isolation and a 1.3 dB nominal insertion loss with good flatness. The return loss of the isolator is 14 dB. The input and output ports are WR-34 waveguides with UG-1530/U flanges.
CABLES & CONNECTORS
MilesTek’s low-smoke zero-halogen (LSZH) MIL-STD-1553B cable assemblies were specifically designed to address confined space connectivity applications. Typically used in poorly ventilated areas, low-smoke zero-halogen cable jackets are used in applications where it is critical to protect people and equipment from toxic and corrosive gases in the event of a fire. To address these applications MilesTek now stocks 78 Ω Twinaxial and 50 Ω Triaxial LSZH cable assemblies with TRB 3-slot plug, blunt end, insulated and non-insulated bulk head 3-Lug connectors.
X-Band Solid-State Power Amplifier Module
COMTECH PST introduces a new GaN amplifier for applications in the X-Band radar market. The AB linear design operates over the 9.2 to 10 GHz frequency range intended for use in radar applications. The amplifier design features include options for control of phase and amplitude to allow for integration into high-power systems utilizing conventional binary or phased array combining approaches for power levels of up to 10 kW.
