LO = 450 MHz
Range over which uncompensated sideband suppression < −30 dBc
Low frequency
High frequency
VIQ = 1.4 V p-p differential
POUT − (fLO + (2 × fBB)), POUT = 6.2 dBm
POUT − (fLO + (3 × fBB)), POUT = 6.2 dBm
f1BB = 3.5 MHz, f2BB = 4.5 MHz, POUT = −2 dBm per tone
f1BB = 3.5 MHz, f2BB = 4.5 MHz, POUT = −2 dBm per tone
I/Q inputs = 0 V differential with a 500 mV common-mode bias,
20 MHz carrier offset
6 MHz carrier offset, POUT = 6 dBm, PLO = 6 dBm
Characterization performed at typical level
