Pin 13.Pin 13 has no connection and should be left open circuit. V 1 (Pin 4).V 1 is the collector bias for the first amplifier CC CC stage in the SKY65111.Multiple bypass capacitors,C3-C5,C17 V 2 (Pins 15-16).V 2 is the collector bias input for the second CC CC and a series inductor,L2,have been utilized to ensure stability amplifier stage in the SKY65111.Multiple bypass capacitors, both in and out of the useable bandwidth of the device.The C8-C10 have been utilized to ensure stability both in and out of length of transmission line between L2 and Pin 4 is not critical; the useable bandwidth of the device.Capacitor C7 is not popu- L2 can be placed as close to the pin as possible if desired. lated with the normal tuning configuration described above. However,placement of L2 farther away from Pin 4 than shown on the Applications Circuit is not recommended.C3 should also be placed in the approximate location shown on the Applications Circuit,but placement is not critical. V 1 (Pin 5).V 1 is the bias control voltage input for amplifier APC APC stages 1 and 2.Nominal operating range is between 2.6 V and DC 2.8 V ,with 3 V producing the minimum attenuation point. DC DC V 1 may also be set to 0 V ,to force stages 1 and 2 into APC DC standby mode. V 2 (Pin 6).V 2 is the bias control voltage for amplifier APC APC stage 3.Nominal operating range is between 2.6 V and DC 2.8 V ,with 3 V producing the minimum attenuation point. DC DC A 100 pF capacitor (C19) may be used for bypassing at high frequencies.The value of this capacitor may also be made large, greater than 1000 pF,if longer response time is acceptable. V 2 may also be set to 0 V ,to place amplifier stage 3 into APC DC standby status. NOTE:In most applications V 1 and V 2 pins are directly tied APC APC together and biased from the same control voltage.V 1 APC and V 2 may also be split if independent control is APC desired.
