Specifications
Product Description
The AG604-89 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG604-89 typically provides 21
dB of gain, +33.5 dBm Output IP3, and +19.5 dBm P1dB.
The device combines dependable performance with
consistent quality to maintain MTTF values exceeding 100
years at mounting temperatures of +85
°
C and is housed in
a SOT-89 industry-standard SMT package.
The AG604-89 consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT technology process
technology and only requires DC-blocking capacitors, a
bias resistor, and an inductive RF choke for operation.
The broadband MMIC amplifier can be directly applied to
various current and next generation wireless technologies
such as GPRS, GSM, CDMA, and W-CDMA. In addition,
the AG604-89 will work for other various applications
within the DC to 2.7 GHz frequency range such as CATV
and fixed wireless.

2. 3OIP measured with two tones at an output power of +2Bm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. The junction temperature ensures a minimum MTTF rating of 1 million hours of usage.
