Figure 16. Double Sideband Output Spectrum.
LO = -12 dBm at 900 MHz. The Test Setup is Shown
in Figure 17.

HPMX-2003 Single and
Double Sideband
Performance
Single sideband (SSB) and double
sideband (DSB) tests are some-
times used to evaluate modulator
performance. Figure 17, below,
shows the test equipment setup
that was used to create the SSB
and DSB output spectrum graphs
(figures 15 and 16).
The phase shift provided by the I
and Q signal generators must be
very close to 90 degrees and the
amplitude of the two signals must
be matched within a few millivolts
or results will not accurately re-
flect the performance of the
modulator IC.
The I, Q signal generator must put
out low distortion signals or the
output spectrum will show high
harmonic levels that reflect the
performance of the signal genera-
tor, not the modulator.
HPMX-2003 Typical Sideband Performance Data
SSB: VIref = VQref = 2.5 V, VImod = VIref +1.25 sin (2π f t), VQmod = VQref + 1.25 cos (2π f t), f = 25 kHz
DSB: VIref = VQref = 2.5 V, VImod = VIref +1.25 cos (2π f t), VQmod = VQref + 1.25 cos (2π f t), f = 25 kHz
