Samtec, the service provider for the connector industry, has enhanced its open-pin-field arrays to simultaneously run analog, digital, and power signals.

New reference designs allow Samtec’s proven high-performance connector arrays, such as the SEARAY, to support analog signals.

Intended for use in high-density RF applications, the new Analog over Array reference designs allow dense, open-pin-field connectors to support digital and analog differential or single-ended signalling, as well as power. These high-density array connectors are already proven in high-speed, high-performance digital and power applications; now, their differential ground pattern can be used to support RF SOCs and applications such as 5G wireless, remote PHY/MSOs, phased array radar, test and measurement, and LEO/MEO satellites.

Performance is specified at:

  • 8GHz bandwidth
  • 50ohm system impedance for single-ended; 100ohm for differential
  • Return loss of -12dB up to 4GHz; -10dB up to 8GHz
  • Crosstalk isolation between channels: -69dBc to 4GHz, -63dBc to 8GHz

The reference design includes recommended pin mapping as part of a full characterisation report. Additional reference designs are in development for applications out to 40GHz.
