Figure 6 shows the SL2030 in a typical upconverter application.
The network connected to RF input pin 7 and pin 8 is to
improve the matching between the device input and the
source. The source would normally be from a cable, via
passive LPF and PlN-diode attenuator all designed for 75Ω
characteristic impedance.
The network connected to the LO pin 12 and pin 13 is a
varactor diode loaded resonant microstrip line resonator.
Fine adjustment of the tuning range can be achieved by
shortening the line (top end) or by physically moving C19
(see Figure 6) closer to the LO pins. This extends the
bottom end of the tuning range.
The network connected to the IF output pin 1 and pin 16 is
a broadband tuned balun centred typically on 1·1 GHz.
This matches the device output impedance of nominally
400Ω (balanced) to 50Ω (unbalanced).
It is important to provide good decoupling on the 5V
supplies and to use a layout which provides some isolation
between the RF, IF and LO ports.
