VEE supply for the mixer IF output.
1st Mixer Outputs
The Mixer is a differential open collector output
configuration which is designed to use over a wide
frequency range. The differential output of the mixer
has back to back diodes across them to limit the
output voltage swing and to prevent pulling of the
VCO. Differential to single–ended circuit
configuration and matching options are shown in
the Test Circuit. Additional mixer gain can be
achieved by matching the outputs for the desired
passband Q.
On–board VCO Transistor
The transistor has the emitter, base, collector, VCC,
and VEE pins available. Internal biasing which is
compensated for stability over temperature is
provided. It is recommended that the base pin is
pulled up to VCC through an RFC chosen for the
particular oscillator center frequency .
2.0 mA 500 µA
VCC, Positive Supply Voltage
A VCC pin is provided for the VCO. The operating
supply voltage range is from 2.7 Vdc to 6.5 Vdc.

2nd Mixer Linearity Control
The mixer linearity control circuit accepts
approximately 0 to 400 µA control current to set the
dynamic range of the mixer. An Input Third Order
Intercept Point, IIP3 of 17 dBm may be achieved at
400 µA of control current. IIP3 default with no
external bias is 10 dBm.
450 µA
2nd Mixer Input
The mixer input impedance is broadband 50 Ω.
