    ...of the mixer conversion loss in the upper (signal) and lower (image) sidebands, named USB and LSB . In this cases only a half of the LO power passes through the diplexer, and the 3- dB power loss is compensated by an attenuator at the carcinotron output. Values of signal loss in the diplexer Ld measured for optimal tuning were within 0.1 -0.6 dB for the 123-166 GHz range.

  • A 22 mA 3.7 dB NF direct conversion receiver for 3G WCDMA
    The second transconduc- tor with an adjustable gm, A2, is based on a variable attenuator with 3 dB steps. In the measurements, the largest clock spurious is <20mV at the output, causing < 0.1 dB degradation in the 3.7dB total NF. ADCs achieve a DNL and INL of 0.27 LSB and 0.18LSB, respectively.
    A 0.1 -μF capacitor is expected on VMID1 for adequate bypassing. The input attenuator is controlled via the three most significant bits (MSBs) of the gain control. Refer to Table 1 for the step size of each of these three LSBs . Gain Bits and Corresponding Gain Step Sizes (in dB .
