Chip Biasing options
This chip is self-biased, and flexibility is provided by the access to number of pads. the internal DC electrical schematic is given in order to use these pads in a safe way.
The two requirements are : N1 : Not exceed Vds = 3.5Volt ( internal Drain to Source voltage ). N2 : Not biased in such a way that Vgs becomes positive. ( internal Gate to Source voltage ) We propose two standard biasing : Low Noise and low consumption :
Vd = 4.5V and B, D, E grounded. All the other pads non connected ( NC ). Idd = 55mA & Pout-1dB = 10dBm Typical. ( Equivalent to A,B,C,D,E F: non connected and Vd=4.5V ; G1=G2=G3=+1.V ). Low Noise and higher output power Vd = 4.5V and B, C, F grounded. All the other pads non connected ( NC ). Idd = 75mA & Pout-1dB = 12dBm Typical..
