Matching/Diplexing Circuit for 2.5 to 2.68 GHz Operation.
Recommended LO IN Port Matching
The LO IN port of the C2304 can be matched into 50 ohms with a lossy network. At 3dBm drive, the
unmatched port is at Z = 5 –15j ohms at 2.278 GHz. Also of note is that this impedance varies somewhat with
the LO drive level. Therefore a narrow band high Q network is not recommended due to inherent
manufacturing variation in LO drive available. The simple network below matches this port over an ~ 10%
bandwidth.

Biasing and Electrical Ground/
Thermal Considerations
Pins 3,4,5,10 and 12 should have ground vias straddling
both sides of the pin solder contact. This insures good
electrical and thermal grounding. If the IF AMP is run at
Idss (DC Grounded IF BIAS pin 14), this pin should be
grounded as described above. It is recommended that a
continuous ground plane be present under the package
to lower pin impedance and maintain similarity with the
matching environment used in the schematic in the
Application Information section. Bias for the IF amplifier
is supplied thru IF OUT pin 14. All ports are DC coupled
to the IC. Pins 2,6 and 13 should be kept at 0V DC to
maintain proper gate voltages. Pin 9 is internally biased
at 5V under normal operation and requires an external DC
block.
