Description
PCB Mount SMA Connector
DC Pin
Chip Capacitor, 0402 Pkg, choose value for
lowest frequency of operation. PCBs are pro-
vided with 100 ~ 300 pF capacitors. User may
jumper capacitor mounting gaps on PCB to
allow operation to “DC”.
100 Ohm Resistor, 0402 Pkg.
HMC270MS8G / HMC270MS8GE
SPDT Switch
The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF ports should have
50 ohm impedance and the package ground leads
and exposed ground paddle should be connected
directly to the ground plane similar to that shown
above. The evaluation circuit board shown above is
available from Hittite Microwave Corporation upon
request.
