Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Each set of frequency conditions requires appropriate matching (see Figure 1). Note 3: The LT5579 is guaranteed to meet specified performance from –40°C to 85°C Note 4: SSB noise figure measurements performed with a small-signal noise source and bandpass filter on LO signal generator. No other IF signal applied. |
