SL2030 High Performance Broadband Mixer Oscillator Preliminary Information DS5116 Issue 2.1 October 1999 Features G G G G G Ordering Information SL2030/IG/MP1S (Tubes) SL2030/IG/MP1T (Tape and Reel) Single Chip Broadband Solution Wide Dynamic Range RF Input Low Phase Noise Balanced Internal Local Oscillator Wide Frequency Range: 50 to 860 MHz ESD Protection 2kV min., MIL-STD-883B Method 3015 Cat.1 (Normal ESD handling procedures should be observed) Applications G G G G Double Conversion Tuners Digital Terrestrial Tuners Data Transmit Systems Data Communications Systems The SL2030 is a bipolar, broadband wide dynamic range mixer oscillator, optimised for applications as an upconverter in double conversion tuner systems. It also has application in any system where a wide dynamic range broadband frequency converter is required. The SL2030 is a single chip solution 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 high IF output is interfaced through appropriate impedance matching to the high IF filter. The RF input preamplifier of the device is designed for low noise figure within the operating region and for high intermodulation distortion intercept so offering good signal to noise plus composite distortion spurious performance. The preamplifier also provides gain to the mixer section and ba...
