Hirose, Plug Coaxial Connector with Switch

MS-147 is designed to operate when an external antenna is connected making it suitable for use as an interface in mobile telephones, Bluetooth, wireless communication and Global Positioning Systems, as well as being suitable for use as an inspection point for Microwave boards.
Hirose's MS-147 is a small co-axial switch that has a height of only 3.9mm, weighs 0.11g and is able to self align itself to within ±0.5mm when mating. Electrically the switch can maintain 0.15dB insertion loss throughout its life of 12000 mating cycles with an operating range of DC to 6GHz.
The right angle cable mounted plug has been designed to be robust and can easily be incorporated into cradle designs."

In today's wireless world, testing of RF devices requires a different approach. The MS-156 coaxial switch and test contact provides a simple and reliable method of inspection for high frequency circuits.
With the contact mounted on the board, performance can be tested by inserting one of the external plugs, this switches the circuit to the test probe allowing accurate testing of the equipment. The MS-156 has a low insertion loss of 0.1dB at 6GHz making it almost transparent. Removal of the test probe will then automatically switch to the internal circuit.
The contact is small, only 2.7mm by 2.7mm and 1.6mm high, weighing only 0.025g it can fit neatly into any design operating up to 6GHz.
A variety of SMA test adaptors are available for hand testing in the laboratory or fully automatic testing on a production line.
