Conditions No signal, Pin 3 open circuit RS = 50 Ω RL = 22 °C Tamb = 22 °C RL = 150 Ω (SL610C/611C) RL = 1.2k Ω (SL612C) Pin 7 0V to 5.1V Current into pin 7 at 5.1V APPLICATION NOTES Input circuit The SL610C, SL611C and SL612C are normally used with pins 5 and 6 connected together and with the input connected via a capacitor as shown in Fig.2. The input impedance is negative between 30MHz and 100MHz (SL610C, SL611C only) and is shown in Fig.3. The source and inductive is should be shunted by a 1k Ω resistor to prevent oscillation. An alternative circuit with improved noise figure is shown in Fig.4. Output circuit The output stage is an emitter follower and has a negative output impedance at certain frequencies as shown in Fig.5. To prevent oscillation when the load is capacitive a 47 Ω resistor should be conncted in series with the output. AGC When pin 7 is open circuit or connected to a voltage less than 2V the voltage gain is normal. As the AGC voltage is increased there is a reduction in gain as shown in Fig.6. This reduction varies with temperature. Fig.4 Alternative input circuit 4 8 3 5 6 Fig.5 Typical output impedance with s/c input (G22) |
