Description

The ADA-2052 can be used as a frequency extender to enhance the frequency range of a <26 GHz synthesizer up to 52 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 -6 to +2 dBm input.

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.

1It is required that the negative bias be applied before or concurrent with the positive bias.

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

3 Suppression and current consumption will vary with bias voltage. Optimal performance is at approximately +4.0 V / -0.6 V.
