Therefore VG1 must be blocked externally at RF IN. The positive DC voltages of VD1, VD2 and VD3 are typically equal. The voltage range is typically between + 5.0 V and + 7.0 V. The negative DC voltages of VG1, VG2 and VG3 are typically equal. The voltage range depends on the wanted drain current. A gate voltage of - 2.1 V will set ID typically to 1.2 A at VD = 7.0 V. In that case ID1 will have about 70 mA, ID2 about 270 mA and ID3 about 900 mA. Data Sheet 3 2001-01-01 GaAs Components CGY 353 Electrical Characteristics Conditions: VD = 7.0 V, TA = 25 C, f = 3425 - 3450 MHz, ZS = ZL = 50 , pulsed operation mode, duty cycle = 30%, unless otherwise specified.

Transmission burst: Each burst has a 500 s nominal duration with 20 dB of raised cosine shaping of 8 s duration at the beginning and the end of the burst. A maximum of three bursts occur in each 5 ms period, but consecutive bursts are separated by a minimum interval of 1 ms. Duty cycle: 30%, 3 bursts per 5 ms frame with a minimum interval of 1 ms between bursts. The modulation signal has a peak to mean envelope ratio of 3.1 dB. Values of S11 and S22 with match as realized on application board.
