NOTES ON TESTING AND SPECIFICATIONS
Note 1 — C C and C T are measured using a capacitance bridge
(Boonton Electronics Model 75A or equivalent).
Note 2 — Noise figure measured with diode under test in tuned
diode mount using UHF noise source and local
oscillator (LO) frequency of 1.0 GHz. The LO power
is adjusted for 1.0 mW. IF amplifier NF = 1.5 dB,
f = 30 MHz, see Figure 5.
Note 3 — L S is measured on a package having a short instead
of a die, using an impedance bridge (Boonton Radio
Model 250A RX Meter).
