Product Description
The AH102 is a medium power gain block
that offers excellent dynamic range in a low cost
surface mount package. The combination of a
signal supply voltage and an internally matched
device makes it ideal for both narrow band and
broadband applications. Superior thermal
design allows the product to achieve +45 dBm
IP3 performance at a mounting temperature of
+85°C with an associated MTBF of >10
7
hours.

Typical parameters reflect AH102 application circuit.
Test conditions unless otherwise noted.
1. T = 25°C, Vdd = 9.0 V, Freq = 800 MHz, 50 ohm system.
2. 3OIP Measured with two tones at an output power of 8 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 slope rule.
