Push-On Coaxial Connectors (PC Card Type
2
Mountable)
MRF01 Series
Modem Card Mounting Example
(A special frame kit has not been manufactured.)
Board Mounting Example
sFeatures
1. Uses a push-on type system which is easy to
engage and disengage. (There is no lock.)
2. Mountable on PCMCIA Type
II
Card
The 3 mm receptacle thickness permits mounting to the
back side of a type II card.
Note that at the time of card mounting, use of 0.15mm
offset of the board mounting surface from the card center
line will result in the same card center axis and connector
center axis.
3. High Degree of Matching
These connectors offer high frequency performance from
0 to 3 GHz with a V.S.W.R. of 1.3 or less.
4. Accommodates Ultra-Fine Cable
Suitable cable ...RG-178B/U (

sApplications
Wireless LAN cards, GPS cards, and miniature wireless
communications devices.

*Voltage
standing wave ratio (V.S.W.R.) measuring system.
The above voltage standing wave ratio (V.S.W.R.) standard value is measured in the measuring system as shown below.
Note1: The cable connector is measured with double ended 10cm cable
assembly.
Note2: The printed circuit board connector is mounted on the 50 ohms PCB, to
which Hirose's adaptor is connected.
