NOTES

1. NC = NO CONNECT

2. CONNECT EXPOSED PADDLE TO A LOW IMPEDANCE

GROUND PLANE.

*THE PADS FOR PIN 28 AND PIN 31 MUST REMAIN FREE

OF TRACES TO AVOID STRAY CAPACITANCE.

Description

1

LOIP

Loopback Mixer Differential LO Input. Should be ac-coupled to the source of the mixer local

oscillator signal.

2

LOIN

Loopback Mixer Differential LO Input. Should be ac-coupled to ground.

3, 21

VCC

Positive Supply. Nominally equal to 5 V. VCC and DVCC must be connected together externally

and be properly bypassed.

4

LOOP OUT

Loopback Mixer RF Output. Single-ended 50 Ω output.

5

LOOP EN

Loopback Mixer Enable. Apply logic high for normal transmit mode. Apply logic mode low for

loopback mode.

6

DATA

SPI Data Input. Both attenuators are programmed with a single 10-bit word.

7

CLK

SPI Clock Input. Data is clocked on the rising edge of CLK.

8

LE

SPI Latch Enable. Data is latched on the falling edge of LE.

9

DVCC

Digital Positive Supply. Nominally equal to 5 V.

12

RFOUT

RF Output. Should be ac-coupled.

39

RFIN

RF Input. Should be ac-coupled.

19, 22, 24 to 26,

30, 32, 35, 37, 38

GND

Common. Connect to a low impedance ground plane.

15, 16, 18, 20, 23,

27 to 29, 31, 33,

34, 36, 40

NC

No Connection. The pad for Pin 28 and Pin 31 must remain free of traces to avoid stray capacitances.

EP

Exposed Paddle. Connect to a low impedance ground plane.
