Description

The ADA-1030 can be used as a frequency extender to enhance the frequency range of a <15 GHz synthesizer up to 30 GHz. Useful for lab testing, test and measurement, and prototype systems. It consists of an input buffer amplifier, doubler, and output buffer amplifier to provide a +16 dBm output (suitable for driving most mixers) from a 0-6 dBm input. In addition to operation as a module, it is suitable as a reference design for prototyping using only commercially available surface mount products.

Specifications

The electrical specifications apply at TA=+25°C in a 50Ω system.

Suppression is relative to doubled output power.  Isolation is defined as relative to the fundamental input power.

1 The positive bias is from +3 to +7 Volts and the negative bias is from -0.25 to ground. The higher positive bias voltage, the better 2F output   converted power will be, and the lower positive bias voltage, the better 1F, 3F harmonic suppression will be.

2 The higher input power the better 2F output power and the worse 1F/3F suppression will be, (see plot 2F Output Converted Power)

3 Suppression and current consumption will vary with negative bias voltage. Optimal performance is at approximately -0.15 V.
