C2, L2: Filter for lower frequency. Each filter is a throughpath for the desired frequency (RF or IF) and isolates the other frequency (IF or RF) and its harmonics. These two filters must be connected to pin 1 and pin 6 directly. Parasitic capacitances at the ports 1 and 6 must be as small as possible. L4 and C4 are optimized by indicating lowest IOP at used LO-frequency; same procedure for L3. The ports 1, 3 and 6 must be DC open.

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 requirements 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 , but performance will degrade at larger deviations. Data Sheet 5 2001-01-01 GaAs Components CMY 211 Note 2 The 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. Note 3 The 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 = 50 ) within this frequency range. The Conversion Noise Figure FSSB is corresponding with the value of Conversion Loss LC. The LO signal must be clean of noise and spurious at the frequencies fLO fIF. Package Parameters Dim.
