  2. Linearity: Distance 1st to second Harmonic of IF 250 to 500 kHz Linearity > 50dB for Rfin < -12dBm

  3. Dynamic behaviour of IF frequency Max Output Level between +3 and +6 dBm for IF of 25 KHz

  4. Crosstalk Crosstalk of < 60 dB

  5. Offset Behaviour Offset < 1mV for RFin < -12dBm Temperture Drift < 1mV/deg C or 0.2 deg RF Phaseshift per 1 deg C

  6. Noise estimation for one channel Downconverter based on AD8343 mixer 500 Ohm 3.3nV/sqrt Hz 2.5nV/sqrt Hz 4.5nV/sqrt Hz (5.6nV/sqrt/ Hz)x 8.5 Mixer1 AD8343 Ampl 1 x8..5 4nV/sqrt Hz ~ 50 nV/sqrt Hz Noise measured with HP 3556A shows 70nV /sqrt Hz in the range 0 to 100KHz Noise for 200 kHz Bandwidth ~ 30 uV rms
