• Manufacturer Part Number: mga-685t6
• Description: Current-adjustable, Low Noise Amplifiers
• Manufacturer: Avago Technologies

MGA-685T6 Typical Performance, Vd = 5V, Ids = 15mA ,R1 = 5.6KΩ as measured in Fig 1a test circuit (unless specifi ed
otherwise)
Figure 39. OP1dB vs Frequency (Vd = 5V, Ids = 15mA)
Figure 41. Gain vs Frequency (Vd = 5V, Ids = 15mA)
Figure 43. Input Return Loss vs Frequency (Vd = 5V, Ids = 15mA)
Notes for Figure 6 ~ 44:
1. Measurement uses the test circuit and circuit schematics shows in Figure 1a.
2. Ids taken at ambient temperature of 25ºC with temperature variation.
3. Bias current (Ids) for the above charts are quiescent conditions. Actual level may increase or decrease depending on amount of RF drive.
