HMC273MS10G / 273MS10GE数字衰减器
The HMC307QS16G & HMC307QS16GE are broadband 5-bit GaAs IC digital attenuators in 16 lead QSOP grounded base surface mount plastic packages. Covering DC to 4 GHz, the insertion loss is less then 2 dB typical. The attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total attenuation of 31 dB. Attenuation accuracy is excellent at ± 0.5 dB typical with an IIP3 of up to +44 dBm. Five bit control voltage inputs, toggled between 0 and -5V, are used to select each attenuation state at less than 50 uA each. A single Vee bias of -5V allows operation down to DC. This product is an excellent alternative to the HMC235QS16G.

The HMC462LP5 & HMC462LP5E are GaAs MMIC PHEMT Low Noise Distributed Amplifi ers in leadless 5 x 5 mm surface mount packages which operate between 2 and 20 GHz. The self-biased amplifi er provides 13 dB of gain, 2.5 to 3.5 dB noise fi gure and +14.5 dBm of output power at 1 dB gain compression while requiring only 66 mA from a single +5V supply. Gain fl atness is excellent from 6 - 18 GHz making the HMC462LP5 & HMC462LP5E ideal for EW, ECM RADAR and test equipment applications. The wideband amplifi er I/Os are internally matched to 50 Ohms and are internally DC blocked.
