PIN Diode Switch
Amplical’s SW12A003 SP12T broadband coaxial absorptive PIN diode switch features 2 to 18 GHz bandwidth with low insertion loss, low VSWR, high isolation and fast switching speed. J1 through J12 ports are terminated in 50 Ω when switched in the isolation (off) state. A 4-bit coded TTL-compatible driver is incorporated for convenient logic control. The switch operates from +5 VDC and a negative DC supply ranging from −12 to −20 V. The compact design incorporates field-replaceable SMA female connectors.
Coaxial Power Divider/Combiner
Cernexwave’s model CDPU5180608T coaxial power divider/combiner has a frequency range of 0.5 to 18 GHz, an isolation greater than 16 dB, a VSWR of less than 1.5:1 with one SMA and female input and 8 SMA female output connectors. It features low insertion loss, low VSWR and high isolation in 2- to 32-way configurations.
Ducommun’s switch cycler is designed to automate switch cycling and allow users to “plug-and-play” versus having to design a custom instrument themselves. The CAT-001 allows users to perform a “burn-in” function for switches that have sat in inventory for long periods of time. The CAT-001 also features an optional strip chart counter to record data for each switch, GUI remote control for automation and a keypad for local control.
Microstrip Filter Designs
Free microstrip filter designs are available in Exceed Microwave’s Microstrip Filter Library for number of sections that are four or less. When you do not have time to design your own planar filters, choose from the company’s library and they will send you the .step file for the design.

Broadband 1.8 GHz Couplers
These 75 Ω couplers are designed for next-gen CATV systems. The MRFCP6762 16 dB coupler is flat to 1.8 GHz and provides 20 dB return loss. Uniquely the 6762 also provides max throughput power with low loss and nearly 30 dB isolation with MiniRF repeatability and reliability.
5G Interference Solution
Norsat’s latest 5G interference solution consists of a C-Band interference suppression LNB and bandpass filter. With the rollout of 5G infrastructure, new cellular base station signals will be powerful enough to saturate sensitive C-Band satellite receiving systems. Norsat’s advanced LNB with internal filtering can mitigate 5G signals and is the perfect solution for broadcasters, media houses and other C-Band operators. For additional filtering, the bandpass filter can be used to reject terrestrial interference within the C-Band.
Pasternack, an Infinite Electronics brand, has expanded its line of broadband, high-power coaxial limiters that are designed to help protect sensitive components in the receive chain and other microwave circuits in close proximity to high-power signals. The typical applications for these RF limiters include EW, military communications, instrumentation, fiber optic communication systems, SATCOM, radar, point-to-point wireless, telecom and R&D applications.
8-Bit Digitally Tuned Attenuator
PMI Model No. DTA-200M18G-100-CD-1 is a 0.2 to 18 GHz, 8-bit digitally tuned attenuator. This unit has a min. attenuation range of 100 dB and a min. attenuation step of 0.5 dB. It is supplied with SMA female connectors and a 15-Pin Micro-D female connector in a housing measuring 4 × 1.8 × 0.5 in.
