Maxim Integrated 

MAX2092

700MHz to 2700MHz Analog VGA with Threshold

Alarm Circuit and Error Amplifier for Level Control

AC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit with analog attenuator set for maximum gain, VCC = 4.75V to 5.8V, fRF = 1835MHz, PRFIN = -16dBm

(CW), TC = -40°C to +95°C, and RF ports are connected to 50Ω sources and loads, unless otherwise noted. Typical values are at

TC = +25°C, VCC = 5.5V, PRF_IN = -16dBm, VPLVLSET = 2.5V, CTRL1 = 1, CTRL2 = 0. Min/max specifications apply over supply,

process, and temperature, unless otherwise noted.) (Notes 5, 7)

Note 5: Production tested at TC = +95°C. All other temperatures guaranteed by design and characterization.

Note 6: Recommended functional range, not production tested. Operation outside this range is possible, but with degraded

performance of some parameters.

Note 7: All limits include external component losses. Output measurements are taken at the RF port of the Typical Application

Circuit.

Note 8: It is advisable not to continuously operate the VGA RF-input above +12dBm.
