Ventura, California – March, 2005

Dow-Key Microwave (a subsidiary of Dover Corp., NYSE:DOV), is an ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, Switch Matrices, Integrated Modular Assemblies, and related passive components. The company”s newest product release is a 3 GHz Bypass Switch.

DC Characteristics of this Bypass Switch include 24-32 VDC operation (28 VDC nominal operating current is 300 mA typical @ 20ºC). Equipped with a failsafe actuator, this device switches in 15 ms (max). The panel side of the switch is equipped with N-Type connectors. SMA connectors are provided for the internal system connections.

This very reliable panel-mounted, bypass switch targets the wireless market. One ideal application is to bypass an LNA (low noise amplifier) or a filter in case of failure. As a panel-mounted switch, the need for two RF cables is eliminated thereby reducing cost and improving system performance.


Typical RF Performance (P/N 411FL-2308-2):

Frequency Range (GHz) DC – 1 1 – 2 2 – 3
VSWR (max.) 1.10:1 1.15:1 1.2:1
Insertion Loss(dB max.) 0.1 0.15 0.2
Isolation: (dB Min.) 80 80 80
RF Power: WCW 100 100 80
