General Description and NotesThe CMY210 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 1Best 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 port1
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 50Ω, but

Note 2The LO-Buffer needs an external inductor L4 at port 4; the value of inductance depends
on the LO frequency. It is tuned for minimum IOP consumption into port 4.
At lower LO frequencies it can be reduced by an additional capacitor C5.
Note 3The LO Input impedance at Port 3 can be matched with a series inductor. It also can be
tuned for a minimum current IOP into port 4. C3 is a DC blocking capacitor.
Since the input impedance of port 3 can be slightly negative at lower frequencies, the
source reflection coefficient should be kept below 0.8 (Z0 = 50Ω) within this frequency
range.
The Conversion Noise Figure FSSB is corresponding with the value of Conversion LossC. The LO signal must be clean of noise and spurious at the frequencies fLO±fIF.
