Notes
1. GUM is the maximum unilateral power gain, assuming s12 is zero and GUM = 10 log (---1-----–------s---1---1---s-2---2)--1(---1-2----–------s---2--2-----2---) dB.
2. VCE = 8 V; IC = 40 mA; RL = 50 Ω; Tamb = 25 °C;
fp = 900 MHz; fq = 902 MHz;
measured at f(2p − q) = 898 MHz and f(2q − p) = 904 MHz.
3. dim = −60 dB (DIN 45004B); IC = 40 mA; VCE = 8 V; ZL = ZS = 75 Ω; Tamb = 25 °C;
Vp = VO; Vq = VO −6 dB; Vr = VO −6 dB;
fp = 795.25 MHz; fq = 803.25 MHz; fr = 805.25 MHz;
measured at f(p + q − r) = 793.25 MHz.
4. IC = 40 mA; VCE = 8 V; VO = 275 mV; Tamb = 25 °C;
fp = 250 MHz; fq = 560 MHz; measured at f(p + q) = 810 MHz.
