GENERAL INFORM
ATION
Bi-Phase modulators shift the phase of an RF signal
b
y 180 upon appl i-
cation of a TTL logic signal .Logic 0 produces a re f
erence ( 0) phase and
logic 1 changes the phase 18 0
. Bi phase modulators can be used in ca
r
-
rier suppression system
s
. If an RF signal at a frequency f
a is applied to
the RF te rminal, and a square w
ave modulating signal, fm, is applied to
the bias te rminal ma ny frequencies are gene r
ated at the RF output .They
are fa, fa fm, fa2 fm fanfm .The car rier, fa is suppressed a mini m
um
of 20 dB on all model s
. Typical supression on most models is 30 d
B
. The
first order sidebands are each d
o
wn appr oximately 4 d B., plus inse rtion
los s. The even sidebands are d o
wn 25 d B, and the odd sidebands are as
foll ows:
3rd order sidebands--10 dB
5th order sidebands--14 dB
7th order sidebands--18 d B
, etc.

Frequen c
y Ran ge: 0.20 to 18.0 GHz
RF Impedance:
50 Ohms
D.C . Requirements:
For modulators with d r
ivers, +5 Volts
at +80 mA and 5 Volts at 80 mA .(Logic
0, referenc e. Logic 1, 18 0.
RF Power: 0.2 watts average, 10 watts peak.
Temperature In
f
ormation: Operating tempe rature from 5 5C to
+85C.
Swit ching Speed: Standard switching speed f
or all models
is 500 nanosec .(750 nanosec.including
sto rage and del ay time) .Any model can
be switched in 35 nanoseconds (inclu
d
-
ing sto rage and del ay time) if required.
However, the inse rtion loss will increase
b
y
30%. If 10 nanoseconds is required add--
1 to the model number when orde r
ing.
