Application Information
Application Input Power Comments T3 LO Driver +10 to +15 dBm Ideal choice for driving all T3 mixers down to 10 MHz. When driven beyond the 1 dB compression point (with inputs higher than 10 dBm), it will create a saturated square wave output that improves the IP3, spurious suppression, and 1 dB compression of the T3 mixer, especially at lower frequencies. Broadband Mixer LO Driver -5 to +10 dBm Can be used to drive any double balanced mixer with an H diode or lower (including L, I, and M diodes). For this purpose saturated operation is not preferred, and may cause undesirable results. Input power should be kept in the -5 to +10 dBm range to provide appropriate output power, depending on the mixer. General Purpose Linear RF Amplifier <+5 dBm Can be used as a general purpose amplifier for RF signals. Input power should be kept below +5 dBm for linear operation.

BROADBAND DISTRIBUTED AMPLIFIER ADM1-0026PA Page 8 Frequency 5 MHz to 26.5 GHz Biasing and Operation Positive Bias (Vd) –Bias supply on Vd should be voltage limited below 9 V and current limited below 250 mA at all times. The operational bias voltage should be between 3 V and 7 V for full gain, efficiency, and linearity. In general linearity and output power will increase marginally with increased voltage from 3 to 7 V. DC/RF Ground – The ground lug or case should be attached to the DC power supply ground at all times. Negative Bias (Vg)- Bias on these pins is recommended. Application of a negative bias can reduce the current draw from the positive supply, slightly improve small signal gain at higher frequencies, significantly improve even order harmonic suppression, and improve nonlinear performance of a T3 mixer. Due to the reduced current, it may also extend the lifetime of the amplifier. The amplifier is designed to perform optimally when the negative bias voltage is adjusted so that the amplifier draws 150 mA on the positive supply. Heat Sinking – Heat sinking is recommended to extend the lifetime of the amplifier whenever the amplifier will be operational for extended periods of time, particularly at elevated temperatures or when the negative bias is grounded.
