Description
The SKY73070 is a fully integrated single mixer that includes a
Local Oscillator (LO) driver, high linearity mixer, and large
dynamic range Intermediate Frequency (IF) amplifier. A low loss
RF balun has also been included to reduce design complications
and lower system cost.
The SKY73070 features an input IP3 of +27.0 dBm and a Noise
Figure (NF) of 8.3 dB, making the device an ideal solution for high
dynamic range systems such as 2G/3G base station transceivers.
The SKY73070 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73070 single downconversion mixer is provided in a
compact, 20-pin 5 x 5 mm Multi-Chip Module (MCM). A functional
block diagram is shown in Figure 1. The pin configuration and
package are shown in Figure 2. Signal pin assignments and
functional pin descriptions are provided in Table 1.
