3 / 13 page Intermediate Frequency Digital Variable Gain Amplifier IDTF1200 RevO Page 3 of 13 April, 2011 DATASHEET IDTF1200 SPECIFICATION VCC = +5.0V, fRF = 100MHz, TC= +25°C, STBY = GND, R6 = 2.87K +/-1%, POUT = +3 dBm, unless otherwise noted in the condition column. EVkit trace, transformer & matching losses are de-embedded for specification purposes (note: de-embedded losses = 0.4dB input and 0.4dB output at 100MHz). Parameter Condition Symbol min typ max units Operating Temp.
