V.
Total system with final load as in Figure 7, including an interstage IF shaping filter with IL of 2 dB and
characteristic impedance of 200
differential.
The specified gain is determined by the following formula;
Gs = Gm + Vtr where
Gs = gain as specified
Gm = gain as measured with specified load conditions
Vtr = voltage transformation ratio of transformer as in Figure 7
Two input tones within RF operating range at -14 dBm from 50
single ended source with 200
differential output load. DC output
current must be shunted to Vcc through suitable inductor, i.e. 10
μ
H.
Modulation spurs introduced on local oscillator through injection locking of the local oscillator by an
undesired RF carrier.
Desired carrier at 80 dB
μ
V, undesired carrier at 90 dB
μ
V at an offset frequency of f
d
plus 42+f
c
MHz,
where f
d
is desired carrier frequency, f
c
is US chrominance sub carrier and 42 equals 7 channel spacings.
All intermodulation specifications are measured with a single-ended input.
Operation range is defined as the region over which the oscillator presents a negative impedance.
Target to achieve 6 dB minimum S11.
