Product Description
Functional Diagram
The AH31 is a high dynamic range amplifier in a
low-cost surface-mount package. Its robustness and
ease of use make it an ideal candidate for the core of any
RFID reader application. It is compliant with EPC and ISO
standards. The combination of low noise figure, high
gain, and high output IP3 is ideal as an IF amplifier
for receiver and transmitter applications. The device
combines dependable performance with consistent
quality to maintain MTTF values exceeding 100
years at mounting temp eratures of +85°C and is
housed in a SOT-89 industry-standard SMT package.
The broadband MMIC amplifier can be directly applied to
various current and next generation RFID technologies
such as EPC, ISO, ETSI, and ANSI. Their small size
makes them ideal for PCMCIA applications.

Test conditions unless otherwise noted.
1. T = 25ºC, Vdd = +5 V, Frequency = 240 MHz in a tuned application circuit.
2. 3OIP measured with two tones at an output power of +10 dBm/tone separated by 1 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.
