B BROADBAND DISTRIBUTED AMPLIFIER ADM-5931CH Page 2 Frequency DC to 28 GHz Functional Diagram Biasing and Operation RF In / RF Out – Input and output signals should be connected by 50 ohm microstrip or coplanar traces to well matched 50 ohm sources and loads. DC blocking capacitors and bias tees are required. Vg – Negative gate voltage is optional to improve lifetime of the amplifier and reduce current consumption. Harmonic generation is also significantly affected by the negative gate voltage level. It may be supplied through the Vg pad or through the RF input pad using an external bias tee Vd- It is recommended that bias voltage Vd is applied through a bias tee on the RF output, but bias supply can also be supplied to Vd through Vd2 pad if desired. This will result in increased operating temperature and slightly reduced gain and power output. Bias supply should be voltage limited below 9 V and current limited below 150 mA at all times. The operational bias voltage should be between 3 V and 7 V for full small-signal gain, or between 5 V and 7 V for full gain, linearity and power output. If bias tee on RF output is used, pad Vd2 voltage should be left unconnected (not grounded). Bias Circuitry – The capacitors on the Vd and Vg lines prevent low frequency oscillation. They may be reduced or omitted in bias circuits with sufficient low-frequency loss. Designers are encouraged to experiment if they want to modify or omit the bias circuitry. DC/RF Ground – The back of the chip should be connected to a low noise RF and DC ground with very low electrical and thermal resistance for high frequency operation and thermal heat sinking. Warning: GaAs MMIC devices are susceptible to Electrostatic Discharge. Use proper ESD precautions when handling these items.
