3D BGX7100
Transmitter IQ modulator
Rev. 5 — 3 September 2012
Product data sheet
1. General description
The BGX7100 device combines high performance, high linearity I and Q modulation paths
for use in radio frequency up-conversion. It supports RF frequency outputs in the range
from 400 MHz to 4000 MHz. The BGX7100 IQ modulator is performance independent of
the IQ common mode voltage. The modulator provides a typical output power at 1 dB gain
compression (PL(1dB)) value of 12 dBm and a typical 27 dBm output third-order intercept
point (IP3o). Unadjusted sideband suppression and carrier feedthrough are 50 dBc and
45 dBm respectively. A hardware control pin provides a fast power-down/power-up mode
functionality which allows significant power saving.
2. Features and benefits
400 MHz to 4000 MHz frequency operating range
Stable performance across 0.25 V to 3.3 V common-mode voltage input
Independent low-current power-down hardware control pin
12 dBm output 1 dB compression point
27 dBm output third-order intercept point (typical)

Figure 4 shows a typical wideband (from 0.4 GHz to 4 GHz) application circuit. Refer to
the application note for narrowband optimum component values.
12.1 External DAC interfacing
Nominal DAC single-ended output currents are between 0 mA and 20 mA.
If the DAC outputs are only designed for 1 V peak-to-peak differential (250 mV
peak-single) then the single-ended impedance at the DAC needs to be limited to 25 .
This can be split as 50 load resistors at the DAC outputs and a 225 differential
resistor in parallel to the modulator inputs (see Figure 5). In this way, the differential filter
can be properly terminated by 100 at both ends.
If the DAC outputs can withstand a higher swing without performance degradation, then
90 load resistors can be placed at the DAC outputs. No external resistors are needed in
this case, only the differential filter needs to be designed to have 180 at both ends (see
Figure 6).
