有人可以向TI反馈，测试并公布最佳阻抗值？ TI 只公布868波段的最佳匹配阻抗。
Single-Ended TX Only
Load pull measurements show that maximum output power can be achieved if the single-ended RF pin
sees 14 – j20Ω. A suggested matching network is shown Figure 3. This match gives an output power of
11.8 dBm, 2nd harmonic of -39 dBm, and 3rd harmonic of -42 dBm (measured on 3 units @25°, 3.0 V,
868 MHz). Note that single-ended measurements have not been done for 433 MHz. |
