Ventura, California — February, 2002 – 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. Its” newest product is the CANBus-based Switch Matrix (PIN 4101 -ENET) equipped with a built-in Ethernet port. This Switch Matrix is designed with a highly modular structure, permitting rapid assembly of customized systems.

The 4101-ENET performs up to 18 GHz, providing a bi-directional switch matrix that can be configured with up to 10 inputs and up to 10 outputs. Users can easily access this matrix from anywhere in the world via TCP/IP protocols on 1OBaseT networks. Each unit is equipped with an LCD front panel display and keypad for manual override and the Ethernet (802.3 3). Housed in a low profile (7″ 4U) 19″ rack mountable chassis, this CANBus switch matrix occupies less rack space than competitive systems. In addition, the enclosure and power supply is matched for EMI integrity. Available options include type N or BNC Connectors.


Frequency Range (GHz) DC – 8 8 – 12 12 – 18
VSWR (Max.) 1.4:1 1.6:1 1.8:1
Insertion Loss (dB max.) 3.0 4.5 6.0
