Dow-Key RF Switch Matrix Products

Offering Standard and Custom Solutions

Designed and developed for commercial and military environments, our RF Switch Matrix Products offer a variety of high density, RF Switching (Tx and Rx) configurations including low/high frequency, low/high power, narrowband and broadband solutions from DC to 40GHz. Units can be equipped with active or passive components in addition to any switches.

An ideal choice for ATE, SATCOM and mission critical applications, our custom offerings can be designed around electromechanical and/or solid state products in order to meet demanding specifications for high isolation, low insertion loss, VSWR, as well as switching time.

Test & Measurement Solutions

Catering to the ATE market, our Miniature Multiple Switch Matrix (MMS-Series) offers an extensive life and high repeatability. This matrix is populated with CANbus controlled Reliant Switches™ and offers a complete solution best suited to support the 5G network, expand test labs or as a VNA Port Extender to test DUT in high volume production environments.

MS-SERIES:

Multiple Switches: The matrix
is populated with individual
RF switches.

Multiple Switches: The MS-Series is a switch solution populated with Individuals switches to allow the user to control multiple coaxial switches easily through software 

  • Terminated and non-terminated options available
  • SMA or N-Type connectors
  • Built-in firmware to add, remove and address switches for trouble free switch replacement
  • Application configuration available
  • Keeps track of the life of each switch
  • Field upgradeable firmware
  • Can offer as Solid State or Fiber Optic

MP-SERIES:

Multiplexer: An input goes to multiple outputs OR multiple inputs are routed to a single output.

Multiplexer:The MP-Series is a solution with the capability to switch one input to as many as 143 outputs. The input/output ports are bidirectional. 

  • Terminated and non-terminated options available
  • SMA or N-Type connectors
  • Built-in firmware to add, remove and address switches for trouble free switch replacement
  • Application configuration available
  • Keeps track of life of each switch
  • Field upgradeable firmware

CB-SERIES:

Crossbar (non-blocking): Any input can be connected to any unique output (ONE-TO-ONE relationship).

Crossbar (Non-Blocking): A crossbar system can rout any input signal to any output port such that the path between the I/O ports is unique at any given time. It allows testing of multiple UUT/DUT without having to connect and disconnect from the test set-up. 

Fiber Optic: Switches input-to-output paths in pure optical domain with an operating wavelength of 1530-1565 nm in

  • Terminated and non-terminated options available
  • SMA or N-Type connectors
  • Built-in firmware to add, remove and address switches for trouble free replacement
  • Application configuration available
  • Keeps track of life of each switch
  • Field upgradeable firmware
  • Can offer as Solid State or Fiber Optic

SOLID STATE:

Solid State: As a full solid state fan-out matrix, the input RF signals are amplified and divided across every output such that each input signal can be switched to all output ports simultaneosly. 

  • Operates on L-Band, VHF-band, IF-band or HF-band
  • Configurations range from 2X2 up to 12X12
  • LCD Touchscreen
  • Redundant power supplies
  • LED monitoring

Build Your Own Solution:

Electromechanical Controller

The MS-Controller offers an ideal switch set-up allowing anyone to build their own matrix solution by plugging-in Dow-Key CANbus switches onto the rear panel. 

The MS-ENET and MS-GPIB kits are low budget solutions for users who are comfortable to assemble components on their own to build a RF switch solution.

  • Controller converts CAN interface to Ethernet or GPIB
  • Outfitted with 24 RJ11 ports to support 24 CANbus switches
  • Expandable to support additional switches as needed
  • LCD with Keypad manual control
  • RoHS compliant
  • RF switches purchased seprately
  • PCB board controls up to 20 Dow-Key RF switches
