NOTES:
1. Tx inputs are differential sine wave, 0.5 V peak, with quadrature relationship between I and Q Tx input. The output spectrum will be SSB.
The tone is at a frequency of 1 MHz.
2. The output current in each arm is the same but 180 degrees out of phase with each other. Also the tuned load of 400 ohms differential, is
assumed. The power delivered to 400 ohms will be –10.4 dBm (typ.). The output current measurement is indirect based on output power
measurement according to P = 10 log I²rms (400W)/IMV. See typical performance characteristic curve.
3. This is measured with respect to the SSB output.
4. Guaranteed by design and or characterization but not final tested.
5. The input bandwidth may be verified by measuring the output THD and signal level using a DSB spectrum where I = Q.
6. Measured over temperature and supply.
