telefunken semiconductors U2309B-AFS rev. a1: 20.09.1995 4 (8) 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 ohm. all other impedance for rf tests is 50 . 2) the noise figure (nf) is the value for doublesideband measurement. 3) the intermodulation test (2carriermethod) which is made on ifcentre is in reference to a signaltoim 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. application circuit hybrids 0 / 180 degree with 50 ohms z(in) and 100 ohms (2x50) z(out) i/p band c band b band a uhf vhfh vhfl 180 180 i/p i/p l6 15p 10n vs if : pc 38.9 mhz sc 33.4 mhz 1n 1n 1n 1n 1n 1n 1n 1n 100p 100p l.o. l.o. u2309b 1 25 59 21 13 17 the outputvoltage of the if is calculated back to the primary coil of l5 l5 ifout o/p 1n 1n 15p l2 l3 2p2 2p7 1p 1p 1p 1p 68p 1p 2p 18 2p2 2p7 l1 8 turns 3.0 mm dia. l2 3 2.5 l3 3 2.5 l4 3 2.5 air coils 0.6 mm enamelled copper wire l5 12+2 turns l6 6+6 tokocoils 18k bb620 82p l1 1k bb619 18k 18k l4 bb515 8p2 100p 2k2 1n 18k vsw vt 10n o o 95 10718 figure 2. test and principle application circuit note: all component values must be determined application specific. for more detailed information pls. request the application note osemiconductors for tvtuners and the new easylink concepto
