APPLICATIONS INFORMATION  
Evaluation PC Board  
Interface matching between the RF input, RF filter and the  
mixer will be required. The interface matching networks  
shown in the application circuit are designed for 50 Ω  
interfaces.  
The evaluation PCB is very versatile and is intended to be  
used across the entire useful frequency range of this device.  
The PC board is laid out to accommodate all SMT  
components on the circuit side (see Circuit Side Component  
Placement View).  
Differential to single–ended circuit configuration is shown  
in the test circuit. 6.0 dB of additional mixer gain can be  
achieved by conjugately matching the output of the  
MiniCircuits transformer to 50 Ω at the desired IF frequency.  
With narrowband IF output matching the mixer performance  
is 3.0 dB gain and 12 dB noise figure (see Narrowband 49  
and 83 MHz IF Output Matching Options). Typical insertion  
loss of the Toko ceramic filter is 3.0 dB. Thus, the overall gain  
of the circuit is 0 dB with a 15 dB noise figure.  
Component Selection  
The evaluation PC board is designed to accommodate  
specific components, while also being versatile enough to  
use components from various manufacturers. The circuit side  
placement view is illustrated for the components specified in  
the application circuit. The Component Placement View  
specifies particular components that were used to achieve  
the results shown in the typical curves and tables.

16:1 Z Transformer and LC Network  
Mixer Input  
The mixer input impedance is broadband 50 Ω for  
applications up to 2.4 GHz. It easily interfaces with a RF  
ceramic filter as shown in the application schematic.

Mixer Linearity Control

The mixer linearity control circuit accepts approximately  
0 to 2.3 mA control current. An Input Third Order Intercept  
Point, IIP3 of 20 dBm may be achieved at 2.3 mA of control  
current (approximately 7.0 mA of additional supply current).

It is desirable to use a RF ceramic or SAW filter before the  
mixer to provide image frequency rejection. The filter is  
selected based on cost, size and performance tradeoffs.  
Typical RF filters have 3.0 to 5.0 dB insertion loss. The PC  
board layout accommodates both ceramic and SAW RF  
filters which are offered by various suppliers such as  
Siemens, Toko and Murata.
