Preliminary Information
Electrical Characteristics (continued)
These characteristics are guaranteed by either production test or design. They apply within the specified
ambient temperature and supply voltage unless otherwise stated.
Tamb = -20°C to + 70°C, Vee= 0V, Vcc = 4.75V to 5.25V. Desired channel at fc MHz

Notes : 1. Systems specifications refer to total cascaded system of front end converter/AGC stage and baseband amplifier stage
with nominal 6dB pad as interstage filter and load impedance as in Figure 3.
2. AGC set to deliver output amplitude of 108dBµV on desired channel, input frequency fc and amplitude of 79dBµV, with
two interferers of frequencies fc+146 and fc+155MHz at 97dBµV generating output intermodulation spur at 9MHz.
40MHz 3dB bandwidth interstage filter included.
3. AGC set to deliver output amplitude of 108dBµV on desired channel, input frequency fc and amplitude 79 dBµV, with
two interferers of frequencies fc+110 and fc+211MHz at 97 dBµV generating output intermodulation spur at 9MHz.
40MHz 3dB bandwidth interstage filter included.
4. Two tones within RF operating frequency range at 97dBµV, conversion gain set at 4dB.
5. The level of 2.01GHz downconverted to baseband relative to 1.01 GHz with the oscillator tuned to 1 GHz, measured
with no input filtering.
6. The level of second harmonic of 1.01 GHz input at -25 dBm downconverted to baseband relative to 2.01 GHz at -40 dBm
with the oscillator tuned to 2 GHz, measured with no input filtering.
7. Two tones within operating frequency range at 77dBµV.
