Single Control Line Per Bit +/- 0.5 dB Typical Bit Error Miniature QSOP-16 Package: 29.4 mm Electrical Specifications, TA = +25° C, Vee = -5V & VCTL= 0/Vee Typical Applications The HMC307QS16G & HMC307QS16GE are broad- band 5-bit GaAs IC digital attenuators in 16 lead QSOP grounded base surface mount plastic pack- ages. 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 HMC307QS16G / HMC307QS16GE is ideal for:

Choose C1 = C2 = 100 pF ~ 0.1 uF to allow lowest customer specific frequency to pass with minimal loss. R1= 5K Ohm is required to supply voltage to the circuit through either Pin 11 or Pin 14. Bias Voltage & Current Suggested Driver Circuit (One Circuit Required Per Bit Control Input) Simple driver using inexpensive standard logic ICs provides fast switching using minimum DC current. * Recommended value to suppress unwanted RF signals at V1 - V5 control lines.
