APPLICATIONS INFORMATION

typical application circuit in Figure 39. Gain control is possible

can be either left open or capacitively bypassed as shown in

Figure 39.

The recommended bias sequence during power-up is as follows:

typical value).

2. If the gain control function is to be used, apply a voltage

desired gain setting is achieved.

3. Apply the RF input signal.

The recommended bias sequence during power-down is as

follows:

1. Turn off the RF input signal.

Power-up and power-down sequences can differ from the ones

described, although care must always be taken to ensure adherence

to the values shown in the Absolute Maximum Ratings section.

Unless otherwise noted, all measurements and data shown were

taken using the typical application circuit as configured on the

HMC7950 evaluation board. The bias conditions shown in the

Specifications section are recommended to optimize the overall

performance. Operation using other bias conditions may result

in performance that differs from the data shown in this data sheet.
