Features, Applications

Product Features - 870 MHz +41 dBm Output IP3 No Matching Elements Required 3.0 dB Noise Figure 13 dB Gain +20 dBm P1dB MTBF >100 Years SOT-89 SMT Package Single Bias Supply (+5 V)

The is a high dynamic range amplifier for IF requirements. The product achieves low noise figure and high output IP3 at the same bias point, making it ideal for receiver and transmitter applications. In addition, the device is internally matched for 50 ohms in a low cost SOT-89 package. The AH3 is manufactured using GaAs MESFET technology and boasts an MTBF at a mounting temperature of 85C. The package a SOT-89. All devices are 100% RF and DC tested.

Test conditions unless otherwise noted, = 25C, Vdd V, 50 system, 800 MHz. 1. S11 and Noise Figure can be improved using an optional input matching network. 2. OIP3 measured with 2 tones at an output power of +5 dBm/tone separated by 10 MHz. The suppression on the largest IM3 product is used to calculate OIP3 using a 2:1 slope rule. 3. MTBF calculated with ground lead temperature at 85C.
