GENERAL DESCRIPTION

The ADRF5700 is a silicon, 5-bit digital attenuator with 46 dB

attenuation control range in 2 dB steps.

This device operates from 100 MHz to 22 GHz with better than

2.0 dB of insertion loss and high attenuation accuracy. The

ADRF5700 supports bidirectional operation and has a RF input

power handling capability of 24 dBm average and 30 dBm peak for

all attenuation states.

The ADRF5700 requires a dual-supply voltage of +3.3 V and

?3.3 V. The device features parallel mode control, and complementary

metal-oxide semiconductor (CMOS)-/low voltage transistor to

transistor logic (LVTTL)-compatible controls.

The ADRF5700 can also operate with a single positive supply

voltage (VDD) applied while the negative supply voltage (VSS) is

tied to ground. In this operating condition, the small signal performance

is maintained while the switching characteristics, linearity, and

power handling performance are derated (see Table 2).
