Due to the indoor broadband antenna industry news, two diode Bridges were used. Three ports have transformers, so its local vibration, radio frequency and if bandwidth can reach several octave, and large dynamic range, small distortion, high isolation. But its manufacturing cost is high, the process is complex, so the price is high.
For example, HWM82/82C broadband indoor broadband antenna industry news
Main performance indicators:
1) LO 2-18GHz RF 2-18GHz
2) IF 0.03-4GHz
3), the nominal power of the vibration: +13dBm

5) Isolation L-R min 16dB type 20dB (fL 2 to 3GHz), 18dB 30dB (fL 3 to 18GHz), L-I min 20dB type 30dB (fL 2 to 18GHz)
6), frequency conversion compression: +6dBm
7), single tone crossover: 20dbc
8), third-order input crossover: +19dB
9), working temperature: -54 ℃ ~ +100 ℃
10) Storage temperature: -65 ℃ ~ +100 ℃
