Features

The HMC603QS16 & HMC603QS16E are general purpose broadband 5-bit positive control GaAs IC digital attenuators in 16 lead QSOP surface mount plastic packages. Covering 0.7 to 3.8 GHz, the inser- tion loss is less than 1.9 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4 and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excel- l e n t a t ± 0 . 1 5 d B t y p i c a l w i t h a n I I P 3 o f + 5 0 d B m . Five bit control voltage inputs, toggled between 0 a n d + 3 t o + 5 V , a r e u s e d t o s e l e c t e a c h a t t e n u a t i o n state at less than 1 uA each. A single Vdd bias of +3 to +5V applied through an external 5K Ohm resistor is required. 0.5 dB LSB Steps to 15.5 dB Single Positive Control Per Bit ± 0.15 dB Typical Bit Error High Input IP3: +50 dBm Electrical Specifi cations, TA = +25° C, Vdd= +3V to +5V & Vctl= 0/Vdd (Unless Otherwise Stated) Typical Applications The HMC603QS16 / HMC603QS16E is ideal for:  Cellular/3G Infrastructure  ISM, MMDS  WLAN, WiMAX, & WiBro Parameter Frequency (GHz) Min.

Signal lines should have 50 ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
