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).
