U2300B
VHF/ UHF-Tuner-IC
Description
This tuner IC requires a power supply of 12 V and per-
forms the function of three separate oscillators and
mixers, SAWF-driver, L.O.-output and tri-state band
switch. Applications are 12 V TV- and VCR-tuners.
Features
D Frequency range from 48 to 860 MHz
D Band A: balanced high impedance mixer input and
amplitude controlled oscillator
D Band B + C: balanced low impedance mixer input and
symmetrical oscillator
D Balanced L.O.-output for prescalers or PLL
D SAW filter driver with low impedance output
D Voltage regulator for stable operating characteristics
D ESD protection on all pins except oscillator pins and
RF-inputs
Benefits
D The integration of 3 bands allows to design economi-
cal 3-band tuners

Notes
1 The RF input B and C are symmetrical driven by means of a hybrid for 180° phase shifting, consequently the
source impedance is 100 W. All other impedance for RF tests is 50 W.
2 The noise figure (NF) is the value for double-side-band measurement.
3 The intermodulation test (2-carrier-method) which is made on IF-centre is in reference to a signal-to-IM ratio
of 60 dB.
4 Gain is the ratio of the voltage at the primary coil of L5 to the available voltage at the input.
