2.3.4 10 GHz Performance

Figure 2-6 shows a 10 GHz carrier frequency. The performance of all three sources is near identical out to an offset frequency of 1 MHz, which is slightly further than the previous carrier frequencies. An average difference measures as 0.7 dB between the LMX1204EVM and the cascaded LMX1204 design. Refer to Section 2.5 for a comparison of performance in a high frequency application.
