3068N Overview
The CXA3068N is a monolithic IC to down-convert the L-band (930 to 2150 MHz) signal for the satellite broadcasting receiver. It has a double-balanced mixer, local oscillator circuit and IF amplifier on chip.
3068N Key Features
- Balance-type Colpitts oscillator circuit provides a stable and wide range oscillation. Oscillation frequency : 2.63 GHz
- Small leak of the local oscillation signal due to the double-balanced mixer
- Oscillation frequency drift is small, caused by the change of impedance at the pre-stage of RF input
- Local oscillator output circuit for PLL. Single 5 V power supply operation. Low current consumption. ICC=53 mA (typ.) 16
3068N Applications
- Satellite broadcasting tuners for BS, CS, DSS and DVB. (Frequency conversion to the second IF) Structure Bipolar silicon monolithic IC
