STAX™ Coax Connector
Tyco Electronics’ STAX coax connector is
the first surface mount RF coax connector
on the market that uses elastomeric con-
nector technology to provide an economi-
cal means to achieve low board separation
while maintaining excellent RF signal
integrity between PCBs.
The connector uses laminated sections of
conductive and non-conductive silicone that
are tuned to provide a 50 ohm impedance
line between mated substrates.
The single piece construction of the STAX coax connector eliminates some of the signal anomalies
normally associated with mated pairs of metal contact coax connectors. The dimensional rela-
tionship of the inner and outer conductor is consistently maintained throughout the connector.
With its metal holder, the STAX coax connector can be surface mount soldered to the PCB. An
additional metal SMT holder aligns the connector to the mating PCB. If adequate PCB alignment
is already maintained by other means, the coax connector may not need the additional mating
receptacle and can become a blind-mating connector. This has an additional advantage in space
constrained mobile applications where very fine-pitch board-to-board connectors are also used.
