Features G G G G G Ordering Information SL2035/IG/MP1S (Tubes) SL2035/IG/MP1T (Tape and Reel) The output of the preamplifier is fed to the mixer section which is optimised for low radiation application. In this stage the RF signal is mixed with the local oscillator frequency, which is generated by an on-chip oscillator. The oscillator block uses an external tuneable network and is optimised for low phase noise. A typical application is shown in Figure 5. This block also contains a buffer-amplifier to interface with an external PLL to allow for frequency synthesis of the local oscillator. The IF output can be loaded either differentially or singleended. It is remended that the differential load as in Figure 5 is applied as this gives best noise performance. If the output is loaded single-ended the noise figure will be degraded. The approximate model of the IF output is shown in Figure 4. In application care should be taken to achieve symmetric balance to the IF outputs to maximise intermodulation performance. Single Chip Broadband Solution Wide Dynamic Range RF Input Low Phase Noise Balanced Internal Local Oscillator High Frequency Range: 1 to 1- 3 GHz ESD Protection 2k V min., MIL-STD-883B Method 3015 Cat.1 (Normal ESD handling procedures should be observed) Applications Double Conversion Tuners Digital Terrestrial Tuners Data Transmit Systems Data munications Systems The SL2035 is a bipolar, broadband wide dynamic range mixer oscillator, optimised for applications as the downconverter in double conversion tuner systems. It also has application in any system where a wide dynamic range broadband frequency converter is required. The SL2035 is a single chip containing all necessary active circuitry and simply requires an external tuneable resonant network for the local oscillator. The block diagram is shown in Figure 1 and pin connections are shown in Figure 2. In normal application the signal from the high IF output is connected to the RFIN and RFIN...
