The input is designed as high impedance. The circuit contri- butes to suppress spurious signal. Also this symmetrical circuit can keep specified performance insensitive to process-condition distribution. For above reason, double balanced mixer is adopted. 2GND 0 − GND pin. Ground pattern on the board should be formed as wide as possible. Track Length should be kept as short as possible to minimize ground impedance. 3 LOinput − 2.4 Local input pin. Recommendable input level is −10 to 0 dBm. 5VCC 2.7 to 5.5 − Supply voltage pin. 6 RFoutput Same bias as VCC through external inductor − This pin is RF output from DBM. This pin is designed as open collector. Due to the high impedance output, this pin should be externally equipped with LC matching circuit to next stage. 5 6 1 2 3 4PS VCC/GND − Power save control pin. Bias controls operation as follows. VCC GND 5 4 2 Note Each pin voltage is measured with VCC = VPS = VRFout = 3.0 V. Pin bias Control VCC Operation GND Power Save |
