VHF/ UHF-Tuner-IC
U2309B
Description
This tuner IC requires a power supply of 9 V and performs
the function of three separate oscillators an mixers,
SAWF-driver, L.O.-output and tri-state band switch.
Additional to TV-tuner application this IC is usable for
DAB (Digital Audio Broadcast) tuners.
Features
D 9 V supply voltage
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.-outputs 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 and the small SSO28
package allows to design very small and economical
3-band tuners with high performance.

Notes
1) The RF inputs 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.
