A.H. Systems FCC-4 half-wave dipole antenna, consisting of a matching balun, two horizontal elements, and a mounting clamp and tape measure to adjust the element lengths, is the simplest form of antenna.

The QPA1017D is Qorvo’s MMIC power amplifier operating from 5.7 – 7.0 GHz for C-band radar and satellite communications applications. Fabricated on Qorvo’s production 0.15 um GaN on SiC process, the amplifier produces 50 W of saturated output power with 21 dB of large-signal gain while achieving greater than 40% power-added efficiency.

Producing a system that excels in performance and reliability is easy when you have System Design and Applications Engineers with years of experience, Customer Service with global reach, and products that are known for performance and quality. AR has this very organization and product offerings. AR is here for you at each step to ensure that the system design, integration, and support of your EMC or RF system complies with your goals.

The dB-3840 is a TWT Amplifier (TWTA) operating in the frequency range of 34.5 to 35.5 GHz providing 700 Watts minimum peak output power at a duty cycle of up to 10%. A wideband, periodic permanent magnet (PPM)-focused, conduction-cooled TWT is used for power amplification. The power supply topology uses proprietary low-noise, high-efficiency designs to operate the RF signal path. An embedded micro-controller provides the interface, control and protection functions and status indication for the TWT Amplifier. Standard interface protocol for remote operation is RS-485. Other protocols such as RS-232, RS-422, Ethernet, or custom interfaces are available as options. The TWT Amplifier is encased in an environmentally sealed package for outdoor and antenna pedestal mounted applications, and uses integral forced-air cooling for thermal management.

Knowles Precision Devices (DLI) offers filter technology that addresses the challenge of implementing high-performance filters at mmWave frequencies. Their 26 GHz, 28 GHz, and 39 GHz filter solutions deliver 3 GHz of bandwidth, provide greater than 50 dB rejection, and are 20x smaller than current alternatives while implemented in surface mount packages for standard tune-free assembly. They are capable of stable operation within the -55°C to 125°C temperature range. Custom design services are available.

The use of a copper barrier instead of a nickel barrier, with a tin finish on top, is the solution Knowles Precision Services has developed for non-magnetic applications. 

The PT6055 pulsed coupled cavity TWT is an S-band Traveling Wave Tube Amplifier. The Peak Power is nominally 50 kW, the duty cycle 2.4% and the minimum gain 50 dB.

Mimix Broadband’s three stage 18.0-38.0 GHz GaAs MMIC buffer amplifier has a small signal gain of 20.0 dB with a positive gain slope, and a noise figure of 3.5 dB across the band.
