Dual double balanced mixer |
摘要 |
A double balanced mixer for mixing an RF input signal with a local oscillator signal to provide at an output an intermediate frequency signal with a high third order intercept point. A first and second local oscillator balun receives a local oscillator signal. A first and second RF balun receives a RF signal. A first mixer is coupled to the first local oscillator balun and the first RF balun. A second mixer is coupled in parallel with the first mixer. The second mixer is coupled to the second local oscillator balun and the second RF balun. The parallel coupled mixers provide an intermediate frequency signal. A first intermediate frequency balun is coupled to the first mixer and a second intermediate frequency balun is coupled to the second mixer. The mixer also has increased isolation.
