Reference frequency at 23ºC which is computed as mean of the 3 dB frequencies. 2. All dB values are referenced to the insertion loss value. 3. Frequency versus temperature will be according to the following: dFc/Fc = -0.032 ppm * (T-Tc) 2 where (dFc/Fc) = Change in center frequency (in ppm) and T = temperature (in degrees C). Tc = the turnover temperature MAXIMUM RATINGS Parameter Storage Temperature Range Operating Temperature Range (T) Input Power Level Min -40 -40 - Max 85 85 13 Units ˚C ˚C dBm MATCHING CIRCUIT 10 Input 50 Ω Single ended GND All other pads 5 Output 50 Ω Single ended GND Ls1 = 12 nH, Cp1 = 22 pF, Ls2 = 30 nH, Cp2 = 15 pF Notes: • Recommend 2% or better tolerance matching components.
