These SP12T antenna switch modules cover the 0.4-2.7 GHz frequency range. They’re both ideal for applications involving 2G/3G/4G multimode cellular handsets as well as embedded data cards.
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.
The MAS4488 is a broadband matrix switch with an 8 input, 8 output, non-blocking configuration. The system itself is comprised of a processor board, an 8x8 matrix, a LAN interface, a redundant power supply, and manual control.
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.
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 programmed power switch features input current limits of 150mA-2400mA and has a +10% current accuracy at 2A input with its current limit setting. Its Vcc range runs from 2.5V to 5.5V, and its operating temperature range runs from -40 to 85oC.
Dow-Key Microwave’s new Reliant SwitchTM is a 1x6 bidirectional coaxial switch with an operating frequency from DC to 26. 5 GHz, which covers the typical 6 GHz test range and beyond for high-speed testing. This switch is designed with a high isolation of 100 dB (up to 4 GHz) to maintain RF consistency between port-to-port testing. Moreover, the switch can sustain a guaranteed insertion loss repeatability of 0.03 dB across the entire frequency band. This coaxial switch has an extended life cycle where each position can switch a minimum of 5-Million cycles - a 5X improvement from a typical multi-position switch.
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.
