FRONT-ENDS The RF2475 includes two downconverting mixers and associated LNAs. It is designed for IS136 handset applications in the cellular 800MHz and PCS 1900MHz bands. Each LNA has a gain bypass mode, which is controlled by the gain select pin. The device internally ties the two mixer outputs together, providing interface to a single IF SAW filter. A frequency doubler is provided to supply the LO signal to the PCS mixer and feeds the PCS transmit LO output buffer. A cellular LO output buffer is also included. The device is fabricated using Gallium Arsenide HBT technology and is packaged in a 28-pin, 5mmx5mm leadless package. 0.80 0.65 3 Pin 1 identifier must exist on top surface of package by identification mark or feature on the package body. Exact shape and size is optional. 4 Package Warpage: 0.05 mm max. 5 Die Thickness Allowable: 0.305 mm max.

The backside of the package should be soldered to a top side ground pad which is connected to the ground plane with multiple vias. The pad should have a short thermal path to the ground plane. NOTE: The LO doubler is enabled by either MXR VCC19 (PCS RX mode) or TX LO19 (PCS TX mode). VCC DOUBLER is the DC current return path for the output of the doubler. This should be connected to the PLL VCC or a supply that is on in both the TX and RX modes of the 1900MHz band of operation. In the Cellular mode, the doubler is powered down to save current, even when VCC DOUBLER is energized. Therefore, the VCC DOUBLER pin can be connected to a supply that is on in all modes, while minimizing the current consumption of the device. 8-94 Rev A2 010918 RF2475 Preliminary Truth Table of Pin-by-Pin Biasing Pin # Pin Name Biased by VCC Supply Mode 1 28 8 9 12 14 15 16 18 19 22 23 25 LNA VCC19 RX19 VCC LNA OUT19 RX19 VCC LNA VCC8 RX8 VCC LNA OUT8 RX8 VCC MXR VCC19 RX19 VCC TX LO19 TX19 VCC VCC TX19 TX19 VCC DOUBLER VCC PLL VCC IF B IF A IF VCC IF VCC VCC TX8 TX8 VCC TX LO8 TX8 VCC MXR VCC8 RX8 VCC RX-800 L L H H L L L H H H L L H RX-1900 H H L L H L L H H H L L L TX-800 L L L L L L L H L L H H L TX-1900 L L L L L H H H L L L L L L= H= Supply Off Supply On Power Control Modes Mode Pin Name RX19 LNA VCC19 Pin # 1 Controls the Following Circuit Functions 1900MHz LNA Bias MXR VCC19 12 Mixer RF Amplifier Mixer LO Driver RX LO Doubler 16 DC Return for the LO Doubler IF B 18 DC Return for Mixer IF A 19 DC Return for Mixer LNA VCC8 8 800MHz LNA Bias MXR VCC8 25 Mixer RF Amplifier IF B 18 DC Return for Mixer IF A 19 DC Return for Mixer TX8 VCC TX8 22 800MHz TX LO Buffer TX19 VCC TX19 15 1900MHz TX LO Buffer Doubler VCC 16 DC Return for the LO Doubler 8 FRONT-ENDS RX8 Doubler VCC Mixer LO Driver TX LO Doubler NOTES: There are separate RX/TX LO doublers with a common output. The DC return path for both the TX and RX doublers is via the PLL VCC which is on in all TX and RX modes. This allows sharing of the LC load at the doubler output, which saves a significant amount of die area.
