Ducommun’s series of single-pole, double-throw switches covers the DC to 400 MHz frequency range. The switches weigh just 9 ounces and are ideal for integration into MRI machines as well as hyperthermia and ablation equipment.
RLC Electronics’ waveguide switches are available in SPDT and transfer configurations, can be manually or remotely controlled, and offer a choice of coil voltages and optional indicator contacts.
Smartphone users have challenged (and will continue to challenge) mobile networks with the increased amounts of data they download. Though the wireless spectrum is vast, it’s still limited in its availability. Carrier aggregation is a technique that uses two or more bands at the same time to combine spectrum and increase data throughput, giving smartphone users a better data experience. Skyworks recently released two new antenna switches for use in carrier aggregation applications.
This single-pole, double-throw switch covers the 0.01 to 6.0 GHz frequency range and features low insertion loss (0.40 dB @ 2.0 GHz), high isolation (>25 dB @ 2.0 GHz), and single bit control. It’s been designed for mode switching in cellular pre-power amplifier applications or dual-band WLAN (802.11a/b/g/n) applications.
Ducommun offers a variety of manual coaxial switches with variations in type, frequency range, VSWR, insertion loss, isolation, power, and connector type. Shared specifications include 50 ohms (nominal) RF impedance, a 1,000,000 cycle operating life, manual operating models, and an operating temperature range of -35oC to +85oC ambient.
This high-power silicon PIN diode SPDT switch covers the 0.9 to 4.0 GHz frequency range and is ideal for transmit/receive switching in land mobile radios and military communications systems, as well as transmit/receive switching and failsafe switching in TD-SCDMA, WiMAX, and LTE base stations.
This line of SPST and SPDT PIN diode switches feature high power handling, low insertion loss, high antenna-to-receive-isolation, a broad frequency range (20 MHz to 6 GHz), and much more. There are currently nine different SPST and SPDT models available in this series, all with varying maximum power, package sizes, operating frequency ranges, and more.
This Pin switch covers the 20-5000 MHz frequency range and has <0.5 dB insertion loss, >40 dB isolation, <1.4 VSWR, 100 W (peak) power handling, and a <15µs switching speed. For additional specifications and an outline drawing, download the datasheet.
