HMC274 attenuator module wideband digital 5 bit positive control GaAs 0.7 2.7GHz CJMCU 274

Description:
-Hmc274qs16 is a 16 lead qsop plastic package with a broadband 5-bit positive control GaAs integrated circuit digital attenuator. The insertion loss is typically less than 2.3 dB at 2.7 GHz for 0.7 covering. For a total attenuation of 31 dB, the attenuator bit values ​​are 1 (SPEAKERS), 2, 4, 8, and 16 dB. A typical ± 5 dB, IIP3 is up to 50 dBm with excellent accuracy. A five-position control switches between 0 for voltage input and 3 5 volts to select each attenuation state. For a single VDD 3 bias 5 volts is required to be applied through an external 5 K ohm resistor.

Typical applications:
-The HMC27 4qs16 * is ideal:
-Cellular / PCS / 3G infrastructure (2.4 x GHz)
-ISM radio and wireless data

Features:
-31 & pi; for DB × LSB step. dB
-Single positive control ( 3 5 V) /- (0.5) bits per dB
