HMC311ST89ETR

HMC311ST89E is a GaAs InGaP heterojunction bipolar transistor (HBT) gain block MMIC SMT DC to 6GHz amplifier. This amplifier can be used as either a cascadable 50 ohm gain stage or to drive the LO of HMC mixers with upto +16.5dBm output power. It offers 16dB of gain and an output IP3 of +31.5dBm. The darlington feedback pair used results in reduced sensitivity to normal process variations and yields excellent gain stability over temperature while requiring a minimal number of external bias components. It is widely used in application such as cellular / PCS / 3G, fixed wireless & WLAN, CATV & cable modem, microwave radio etc.

• Gain variation over temperature is 0.004dB/°C typ at (DC - 2GHz, TA = +25°C)
• Return loss input / output is 5dB typ at (DC - 2GHz, TA = +25°C)
• Reverse isolation is 20dB typ at (DC - 6GHz, TA = +25°C)
• Noise figure is 4.5dB typ at (DC - 4GHz, TA = +25°C)
• Supply current is 55mA typ at (Vs= 5V, Rbias= 22 ohm, TA = +25°C)
• Supply voltage is 5V
• Operating temperature is -40°C to +85°C
• Package style is SOT89
