GENERAL DESCRIPTION
The HMC939ATCPZ-EP is a 5-bit digital attenuator with a 31 dB
attenuation control range in 1 dB steps.
The HMC939ATCPZ-EP offers optimum insertion loss,
attenuation accuracy, and input linearity over the specified
frequency range from 100 MHz to 33 GHz.
The HMC939ATCPZ-EP requires dual-supply voltages,
V
DD
= 5 V and V
SS
= −5 V, a n d provides a complementary metal
oxide semiconductor (CMOS)-/transistor to transistor level
(TTL)-compatible parallel control interface by incorporating an
on-chip driver.
The HMC939ATCPZ-EP comes in a RoHS compliant, compact,
4 mm × 4 mm LFCSP package.
Additional application and technical information can be found
in the HMC939ALP4E data sheet.
