GaAs MMIC SMT 5 - BIT DIGITAL ATTENUATOR DC - 4 GHz
The HMC235QS16G is a broadband 5-bit
digital attenuator in a 16 - lead (narrow
pitch) surface mount QSOP plastic pack-
age with an exposed ground slug. This
package occupies the same area as an 8
lead SOIC package. The 1, 2, 4 and 8 dB
bits have less than 10 degrees relative
phase shift. The five primary attenuation
states can be activated independently, or
collectively for attenuation levels of 1 to 31
dB. The HMC235QS16G is ideal for cellu-
lar, PCS, WLL, LMDS and IF
applications.This is the smallest 5 bit digi-
tal attenuator available.
