Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Extended application of Absolute Maximum Rating conditions to the device may reduce device reliability.
- Recommended Operating Conditions Parameter Min Typ Max Unit VDD 5 8 V IDD 120 mA Tj for >106 hours MTTF +150 °C Electrical specifications are measured at specified test conditions.
- Specifications are not guaranteed over all recommended operating conditions.
- Electrical Specifications Parameter Condition (1) Min Typ Max Unit Frequency Range DC 1200 MHz Gain 50-1000 MHz 19 dB Gain Flatness +/-0.7 dB Noise Figure 2.0 dB Input Return Loss 18 dB Output Return Loss 18 dB Gain 50-1200 MHz 19 dB Gain.
- There are no on -chip capacitors that limit the low frequency response, enabling the TAT7457 frequency response to extend to DC.
- The open loop gain ( no external feedback) and high frequency gain performance is shown in the plot to the left.
- Best distortion occurs on a 6 V supply; however, for impr oved distortion on a 5 V supply, bias current may be increased by adding a large pull up resistor , R5, of approximately 75 kΩ in parallel with the feedback capacitor.
Topics covered by the datasheet
The document includes sections related to:
- Applications
- Ordering Information
Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
