| Abstract: |
| A novel DarlingtonCascode structure gain block is designed and its op
eration principle is analysed. The simulation results based on AWR Microwave Off
ice show that this structure can achieve a gain expansion for its strong abilit
y of amplifing current, and it can improve the high frequency response with an e
ffect
ive suppression of Miller effect. A gain block with this DarlingtonCascode str
ucture is designed and fabricated based on 2 μm InGaP/GaAs HBT technology. The
measurement results show that over 0.1～4 GHz, its power gain can reach up to
25 dB and the minimum power gain is more than 13.5 dB. At 900 MHz op
eration frequency, its P1dB is 20 dBm. |
