HMC471MS8G General Description

The HMC471MS8G is a SiGe HBT Dual Channel Gain Block MMIC SMT amplifi er covering DC to 5 GHz. This versatile product contains two gain blocks, packaged in a single 8 lead plastic MSOP, for use as either separate cascadable 50 Ohm RF/IF gain stages, LO or PA drivers or with both amplifi ers combined utilizing external 90° hybrids to create a high linearity driver amplifi er. Each amplifi er in the HMC471MS8G offers 20 dB of gain, +20dBm P1dB with a +34 dBm output IP3 at 850 MHz while requiring only 80 mA from a single positive supply. The combined dual amplifi er circuit delivers up to +21 dBm P1dB with +36dBm OIP3 for specific application bands through 4 GHz.

HMC472LP4 General Description

The HMC472LP4 is a broadband 6-bit GaAs IC digital attenuator in a low cost leadless surfacemount package. This single positive control line per bit digital attenuator incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 3.0 GHz, the insertion loss is less than 2.0 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ± 0.5 dB typical step error with an IIP3 of +45 dBm. Six TTL/CMOS control inputs are used to select each attenuation state. A single Vdd bias of +5V is required.

HMC473MS8 General Description

The HMC473MS8 is an absorptive voltage variable attenuator in an 8-lead MSOP package. The device operates with a +3.3V supply voltage and a 0 to +3V control voltage. Unique features include a high dynamic attenuation range of up to 48 dB and excellent power handling performance through all attenuation states. The HMC473MS8 is ideal for operation in wireless applications from 0.45 to 1.6 GHz. Operation from 1.7 to 2.2 GHz is possible with a reduced maximum attenuation of 29 to 32 dB. The HMC473MS8 can be used with an external driver circuit for improved control voltage linearity vs. attenuation.
