The Series 102 is a range of subminiature coaxial reed relays for high
frequency applications up to 3 GHz, performance characteristics will be
found on reverse of this sheet. Two package types are available, both
displaying outstanding RF performance in terms of low insertion loss,
good isolation and excellent VSWR characteristics in 50 ohms systems.
These relays have good coil drive levels making them ideal for portable
applications or where space is at a premium. If an even smaller RF
relay is required, look at the Series 109RF or 111 RF.
For dimensions of
flatpack version, see

102M (Mu-metal) Package.
Switch Ratings
This device, constructed in the popular Single-In-Line format,
features a mu-metal case allowing dense packaging without magnetic
interaction problems. It has six pins for conventional PCB mounting.
With careful printed circuit board layout this configuration will perform
well up to 1.5GHz, it is easy to use and will meet most requirements.

at 200V - Switch No.1
102F (Flatpack) package.
The 102F package dispenses with the leadframe connections to the
switch and screen. These terminations are instead brought out axially
from the ends of the device where they are soldered directly to the
stripline. This technique allows very accurate matching to the 50 ohms
line and gives an excellent VSWR right up to 3 GHz.

TYPICAL PICKERING CONSTRUCTION
Mounting method:
A small rectangular hole is punched into the printed circuit board or
notched into the board edge to accommodate the package. The switch
leads are then soldered directly to the 50 ohms stripline, the tin plated
copper foil from the screen is soldered directly to the ground plane on
the reverse side of the P.C.B. The coil connections are soldered directly
to their tracks in the same way.
