| 1 | IFinput | | 1.2 | This pin is the IF input pin to the double balanced mixer (DBM). The input is designed as a high impedance. The circuit helps suppress spurious signals. Also this symmetrical circuit can keep | |
| specified performance insensitive to process- | | | r |
| condition distribution. For that reason, a double balanced mixer is adopted. | Lo | | | | U |

| 2 4 | GND | GND | GND pin. Ground pattern on the board should be formed as wide as possible. Track length should | JL |
| be kept as short as possible to minimize ground inductance. | 6= | | =H |
| 3 | LOinput | | 2.1 | Local input pin. Recommended input level is -10 t0 0 dBm. |
| 5 | Vcc | 2.7 t0 3.3 | | Supply voltage pin. | = |
| 6 | RFoutput | Same bias as Vcc through external inductor | | This pin is the RF output from the double balanced mixer. This pin is designed as an open collector. Due to the high impedance output, this pin should be externally equipped with an LC matching circuit to the next stage. |
