⢠60-3000 MHz Bandwidth
⢠+37 dBm Output IP3
⢠2.4 dB Noise Figure
⢠14 dB Gain
⢠+18 dBm P1dB
⢠MTBF >100 Years
⢠SOT-89 SMT Package
⢠Single Bias Supply (+3.3 to +4.5 V)
The AM1 is a general purpose gain block that
offers good dynamic range in a low cost surface
mount package. The combination of flat IP3
and noise figure performance over frequency
makes it attractive for both narrow and broad-
band applications. Superior thermal design
allows the product to achieve +37 dBm IP3 per-
formance at a mounting temperature of +85°C
with an associated MTBF of >100 years3. All
devices are 100% RF and DC tested.

Test conditions unless otherwise noted.
1. T = 25°C, Vdd = 4.5 V, Frequency = 800 MHz, 50 ⦠system.
2. OIP3 measured with two tones at an output power of 2 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. MTBF calculated with channel temperature at 155ËC.
