Innovative Modular Micro-D Connectors and Cables for RF, Signal, and High-Speed Data Links

Series GMMD - Glenair Modular High-Speed Micro-D

The Series GMMD is an innovative modular Micro-D connector for RF coax and high-speed differential datalink applications. The unique micro miniature design of the GMMD also accommodates standard analog signal and power contacts, making it the most versatile Micro-D rectangular in the industry. GMMD leverages Glenair Signature Micro-D and Nano TwistPin contact inserts, as well as ultra small form-factor differential twinax modules delivering 18 Gb/second per pair and RF to 20 GHz. GMMD is supplied as factory-terminated pigtails, point-to-point jumpers, and SMT receptacles for easy PCB mounting.

  • Low crosstalk, high bandwidth twinax modules for 18Gb/s per pair and RF up to 20GHz
  • Cable and 90° PCB configurations for matched 100 Ohm differential impedance performance from I/O to board
  • SMT receptacles for easy PCB mounting
  • Combo layouts include twinax, 50 and 75Ω coax, mixed signal and power
  • TwistPin contacts for low resistance and high shock and vibe performance
  • Standard Micro-D shell sizes and hardware

Prevent Mis-Mating with Mod Code 474 Keying Option

Keyed GMMD connectors for "fail-safe" circuits feature specially modified shells to prevent mis-mating. The plug shell has a raised key, and the receptacle shell has a keyway.

The shell size nine connector accommodates three key positions. All other sizes have five positions available. The letter code following Mod Code 474 specifies the key position. "474A" plugs mate to "474A" receptacles.

Keyed plugs will not mate to unkeyed receptacles, but keyed receptacles will plug into standard unkeyed plugs.
