Single-Supply Operation

Figure 10 is similar to the dual-supply circuit in Figure 9. Supplies

may be as low as 9 V but should not be higher than 11 V, due to

power dissipation. As in Figure 9, both the RF and LO ports are

driven single-ended and terminated.

In single-supply operation, the COM terminal is the “ground”

reference for the output amplifier and must be biased to half the

supply voltage, which is done by resistors R1 and R2.The OUT

pin must be ac-coupled to the load.
