General Description and Notes
The CMY 210 is an all port single ended general purpose Up- and Down-Converter.
It combines small conversion losses and excellent intermodulation characteristics with a
low demand of LO- and DC-power.
The internal level controlled LO-Buffer enables a good performance over a wide LO level
range.
The internal mixers principle with one port RF and IF requires a frequency separation at
pin 1 and 6 respectively.
Note 1
Best performance with lowest conversion loss is achieved when each circuit or device
for the frequency separation meets the following requirements:
Input Filter:
Throughpass for the signal to be mixed; reflection of the mixed signal
and the harmonics of both.
Output Filter:
Throughpass for the mixed signal and reflection of the signal to be
mixed and the harmonics of both.
The impedance for the reflecting frequency range of each filter toward the ports 1 and 6
should be as high as possible.
In the simplest case a series- and a parallel- resonator circuit will meet these require-
ments but also others as appropriate drop in filters or micro stripline elements can be
used.
The two branches with filters should meet immediately at the package leads of the port 1
and 6.
Parasitic capacitances at these ports must be kept as small as possible.
The mixer also can be driven with a source- and a load impedance different to 50
Ω
, but
performance will degrade at larger deviations.
