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 |
Dow-Key”s product line of switches range from single-pole single-throw to single-pole 14-throw as well as Transfer, Inline, Waveguide, Switch Matrices, and Integrated Modular Switch Assemblies.
