15. All external circuitry parts are readily available, low cost

surface mount components (.060 in. x .030 in. or .080 in.

x .050 in.).

16. Pin 2 allows use of an external resistor to ground for op-

tional higher current. For 20 mA operation, no resistor is

used.

The spurious table shows the spurious signals resulting from

the mixing of the RFIN and LO input signals, assuming down

conversion. The number of dB below the conversion loss level

indicates

the

mixing

products.

The

lower

frequency

mixing term is shown for two different input levels.

The top

number is for an RFIN power level of –19 dB; the lower

number

is

for

–29

dB.

Assuming

the

LNA

gain

is

approximately 14 dB, the mixer input will see approximately

–5 dB and –15 dB.

RF = 1850 MHz

LO = 1710 MHz
