Description
The SKY12239-11 is a voltage-controlled variable attenuator from
Skyworks series of broadband, flat attenuation, high third order
input intercept point (IIP3) components. The device has been
designed to operate over the 10 MHz to 1.5 GHz frequency band,
and is specifically optimized for use as a wide dynamic range, low
distortion attenuator.
The SKY12239-11 provides monotonic attenuation performance
over its entire control voltage range. This attenuator is comprised
of four matched PIN diodes that are biased using an external
control voltage signal. The attenuator requires no external
components. It operates with a control voltage range of 1 to 5 V
and a 2 mA typical control current at maximum attenuation.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.
