• Manufacturer Part Number: MAX2090
• Description: 50MHz to 1000MHz Analog VGA with Threshold Alarm Circuit and Error Amplifier for Level Control
• Manufacturer: MAXIM [Maxim Integrated Products]

AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit
to +95NC, and RF ports are connected to 50I sources, unless otherwise noted. Typical values are at T
P
unless otherwise noted.) (Note 8)
Note 5: Production tested and guaranteed at T
Note 6: Guaranteed by design and characterization.
Note 7: Recommended functional range. Not production tested. Operation outside this range is possible, but with degraded
Note 8: All limits include external component losses. Output measurements were taken at the RF_OUT port.
Note 9: It is advisable not to continuously operate the RF_IN input power above 11dBm, and RF_OUT power above 19dBm.
