BASEBAND MODE, DSA_IN, LOW BAND

All measurements use DSA_IN as an input and baseband IQ as an output, with the RF low-band settings. DSA_OUT is connected to RF_IN

on-board with a short 50Ω trace.

VDD_BB = 2.5V, all other supplies = 1.8V, and TC = 25°C, unless otherwise noted.

Measurements performed with PRF = −55dBm, PLO = −5dBm, fRF = 29GHz, fBB = 100MHz, fLO = 29.1GHz (lower sideband), maximum gain, RF

LPF setting = 0x00 (highest cutoff), LO tunable filter wideband low settings, and VOCM setting = 0x0C, unless otherwise noted.

Measurements performed with high gain settings (Register 0x194, Bits[1:0] = 0b'11) with on-board matching network, unless otherwise noted.

Measurements performed as single-ended measurements on BB_IP output only, with other outputs BB_IN, BB_QP, and BB_QN terminated in

50Ω loads, unless otherwise noted. Data is corrected for 8.15dB of output matching-network loss and 3dB of differential loss, unless otherwise

noted.
