Current Limit Power Switch: AAT4712

Current Limit Power Switch: AAT4712

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.

Switch Matrices

Switch Matrices

Switch matrices are typically used in the design verification or manufacturing phase of test systems. They’re designed to move signal routing and signal conditioning to a test system’s central location. This makes the characterization of the calibration plane between the DUT and the test equipment simpler, reduces insertion loss, improves signal integrity, and better controls phase issues. They can be used in both commercial wireless and aerospace/defense settings. This page provides an overview of Dow-Key Microwave’s offerings as it relates to switch matrices.

High Temperature OCXOs: VN01 and VN03

High Temperature OCXOs: VN01 and VN03

These OCXOs (oven controlled crystal oscillators) cover the 10 to 50 MHz frequency range and are well suited for applications with high temperature operating environments.

20-500 MHz Pin Switch: JDPSW00205T2

20-500 MHz Pin Switch: JDPSW00205T2

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.

TCXO/VCTCXO For Military Applications

This precision TCXO/VCTCXO acts as the timing reference in radios, satellite terminals, and handheld test equipment. It is designed for environmentally hostile conditions – operation under vibration and temperature extremes – and with the US military’s Size, Weight, and Power (SWaP) initiative in mind.

Temperature Compensated Crystal Oscillator (TCXO): T1243

Temperature Compensated Crystal Oscillator (TCXO): T1243

The T1243 is a temperature compensated crystal oscillator (TCXO) that is designed to deliver ultra-low phase noise performance and outstanding vibration compensation. The T1243 features a noise floor reaching down to -165dBc/Hz, and low acceleration sensitivity options down to to <7 x 10-11/g, and can be used in a variety of communication, instrumentation, and military applications.

Coaxial Switch for RF Testing: Reliant&trade;

Coaxial Switch for RF Testing: Reliant™

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.

Single Control SP2T RF Switch: SKY13453-385LF

Single Control SP2T RF Switch: SKY13453-385LF

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.
