CHARACTERISTICS
Tj =25 °C unless otherwise specified.
Notes
1. dim = −60 dB (DIN45004B); VCE = 8 V; IC = 40 mA; RL =50 Ω;
Vp =Vo; Vq =Vo −6 dB; Vr =Vo −6 dB;
fp = 795.25 MHz; fq = 803.25 MHz; fr = 805.5 MHz;
measured at fp +fq − fr = 793.25 MHz.
2. dim = −60 dB (DIN 45004B); IC = 40 mA; VCE = 8 V; RL =50 Ω;
Vp =Vq =Vo; fp = 806 MHz; fq = 810 MHz;
measured at 2fp − fq = 802 MHz.
3. IC = 40 mA; VCE = 8 V; RL =50 Ω;
Vp =Vq = 225 mV; fp = 250 MHz; fq = 560 MHz;
measured at fp +fq = 810 MHz.
