IBBP
I Channel Baseband Positive Input Pin. Input should be dc biased to approximately 1.2 V.
Nominal characterized ac swing is 1 V p-p (0.7 V to 1.7 V). This makes the differential
input 2 V p-p when IBBN is 180 degrees out of phase from IBBP.
I Channel Baseband Negative Input Pin. Input should be dc biased to approximately 1.2 V.
Nominal characterized ac swing is 1 V p-p (0.7 V to 1.7 V). This makes the differential
input 2 V p-p when IBBN is 180 degrees out of phase from IBBP.
Ground pin for the LO phase splitter and LO buffers.
Ground pin for the LO phase splitter and LO buffers.
LO Negative Input Pin. Internal dc bias (approximately VPS1–800 mV) is supplied. This
pin must be ac coupled.
LO Positive Input Pin. Internal dc bias (approximately VPS1–800 mV) is supplied. This
pin must be ac coupled.
Power supply pin for the bias cell and LO buffers. This pin should be decoupled using
local 100 pF and 0.01
μ
F capacitors.
Enable Pin. A high level enables the device; a low level puts the device in sleep mode.
Ground pin for the input stage of output amplifier.
Ground pin for the output stage of output amplifier.

DC Coupled RF Output. User must provide ac coupling on this pin.
Power supply pin for Baseband input voltage to current converters and mixer core. This pin
should be decoupled using local 100 pF and 0.01
μ
F capacitors.
Ground pin for Baseband input voltage to current converters and mixer core.
Ground pin for Baseband input voltage to current converters and mixer core.
Q Channel Baseband Negative Input. Input should be dc biased to approximately 1.2 V.
Nominal characterized ac swing is 1 V p-p. This makes the differential input 2 V p-p when
QBBN is 180 degrees out of phase from QBBP.
Q Channel Baseband Positive Input. Input should be dc biased to approximately 1.2 V.
Nominal characterized ac swing is 1 V p-p. This makes the differential input 2 V p-p when
QBBN is 180 degrees out of phase from QBBP.
