Description
The SL1710 is a quadrature downconverter, intended for high linearity, low noise digital satellite applications.
It contains all the elements necessary, with the exception of the VCO tuning components, to extract baseband I and Q signals from a QPSK or QAM IF input signal.
Features
- s Wide input frequency range (350-500MHz) s On chip oscillator with varactor tuning or SAW resonator operation capability s Nominal 40dB conversion gain from IF input to I and Q outputs s AGC amplifier with 18dB gain control range s I to Q phase match 90°C to ± 2°, gain match better than 1dB s Low impedance I and Q single ended outputs, with 15MHz ± 1dB BW s Divide by 32 prescaler outputs s Suitable for QPSK and up to 64QAM systems
