For RF and microwave systems that need signal sampling and power monitoring, Filter Technology directional couplers cover 0.4 to 18 GHz with 10 dB or 20 dB coupling, up to 20 dB directivity, and 50 W power handling in a small package. Custom designs are available to customer specifications.

In mobile communication, satellite communication and RF power‑amplifier modules, reflected power caused by antenna‑load mismatch flows back into amplifier circuits, which may lead to unstable PA operation or permanent component damage.

ArduSimple's simpleRTK 4 Optimum is a high-performance, low-power RTK GNSS evaluation board built on the u-blox ZED-X20P module. It supports all-band GNSS signals (L1, L2, L5, and L6) and delivers centimeter-level accuracy with update rates up to 25Hz.

RTK Portable 2 is a small RTK receiver that brings centimeter-level accuracy to many applications. Built on the u-blox ZED-F9P module, it supports dual-band GNSS and connects to smartphones, tablets, computers, and embedded platforms via USB or Bluetooth.

In multi‑system shared‑antenna feed networks, base‑station repeater systems and indoor distribution deployments, it is often required to combine two RF signals into a single antenna port while maintaining sufficient isolation between input ports to prevent crosstalk among transmitters.

Filter Technology's power dividers split one input signal into 2 to 32 equal signals and can also work as power combiners, in SMA, N, TNC, BNC, and 7/16 DIN connector styles from DC to 70 GHz. Standard models offer insertion loss from 1.0 dB, isolation up to 18 dB, and amplitude balance to ±0.4 dB, with custom designs available.

Reverse signal reflection is a major hidden risk that destabilizes systems and damages transmitter modules in private networks, wireless base stations and RF transmission systems. As an essential passive component for link protection, a high-performance circulator largely decides the reliability of the entire RF system.

The Qorvo® QPF4607 is an integrated front end module (FEM) designed for Wi-Fi 7 (802.11be) systems. The compact form factor and integrated matching minimizes layout area in the application. Performance is focused on optimizing the PA for a 5V supply voltage that minimizes power consumption to allow for systems that use digital pre-distortion to achieve the highest linear output...
