Noise Figure LOCAL OSCILLATOR NOTES ON TESTING AND SPECIFICATIONS Note 1 -- C C and C T are measured using a capacitance bridge UHF NOISE SOURCE H.P. 349A DIODE IN TUNED MOUNT (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). NOISE FIGURE METER H.P. 342A IF AMPLIFIER NF = 1.5 dB f = 30 MHz Figure 5. Noise Figure Test Circuit G15-2/2 |
