... The high performance capability of the LO buffer allows the use of a single-ended source, thus eliminating the need for an LO balun. The LT5511 mixer delivers +17dBm typical input 3rd order intercept point at 950MHz, and +15.5dBm IIP3 at 1900MHz, with IF input signal levels of – 5dBm. The input 1dB compression point is typically +6dBm ...

... LT5511 CTIO S – (Pins 1, 16): Differential Inputs for the Local Oscillator Signal. They can also be driven single-ended by connecting one ground through a DC blocking capacitor. For single-ended drive, use LO input, as this results in less interference from unwanted coupling of the LO signal to other pins. These pins are internally biased to about 1.4V ...

... The LT5511 can be used in applications using either a low side or high side LO. LO Input Port The LO buffer on the LT5511 consists of differential high speed amplifiers and limiters that are designed to drive the mixer quad to achieve high linearity and performance at + high IF input signal levels ...

... LT5511 U U APPLICATIO S I FOR ATIO On the evaluation board (Figure 4), 1nF DC-blocking capacitors are used on the IF input pins. A 220pF capacitor on the 50 source side of the input balun is used to tune out the excess inductance to improve the match at 50MHz. To shift the match higher in frequency, this capacitor value should be reduced ...
