Product Description

Functional Diagram

The AH1 is a high dynamic range amplifier

packaged in a low cost SOT-89 surface mount

package. The combination of low noise figure

and high output IP3 at the same bias point

makes it ideal for receiver and transmitter

applications. The AH1 achieves +41 dBm

OIP3 at a mounting temperature of 85˚C with

an associated MTBF of >100 years5. All devices

are 100% RF and DC tested.

The product is targeted for applications where

high linearity is required.

Test conditions unless otherwise noted.

1. T = 25°C, Vdd = 5.0, Freq = 800 MHz, 50 ohm system.

2. OIP3 measured with two tones at an output power of 5 dBm/tone separated by 10 MHz. The

suppression on the largest IM3 product is used to calculate the OIP3 using a 2:1 slope rule.

3. S21 and S11 can be improved in the band of interest using a single input shunt microstrip to

ground.

4. Degradation of OIP3 occurs at low temperatures. Minimum typical OIP3 at -40˚C is +35dBm.

5. MTBF calculated with channel temperature at 155˚C.
