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, V_CC = 4.75V to 5.8V, f_RF = 1835MHz, P_RFIN = -16dBm
(CW), T_C = -40°C to +95°C, and RF ports are connected to 50Ω sources and loads, unless otherwise noted. Typical values are at
T_C = +25°C, V_CC = 5.5V, P_{RF_IN} = -16dBm, V_PLVLSET = 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 T_C = +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.
