Test Point K-K1 and L-L1

IF Receive Signal:

Receive I and Q:

FIGURE 10. IF RECEIVE SIGNAL PRIOR TO SAW FILTER (TEST POINT J)

The intermediate frequency (IF) receive signal is the down- converted receive signal prior to the SAW bandpass filter. The center frequency of this signal is 374MHz with a bandwidth of 17MHz. The power of this signal is directly dependent on the input signal power.

Note that the spurious signal visible below the DS spectrum’s frequency is a harmonic of the 44MHz clock. Much of this level is due to stray pickup in the 500Ω RF probe because of the relatively low signal level present. As such, it will have no influence on receiver performance.

FIGURE 11. RECEIVE I AND Q SIGNALS (TEST POINTS K AND L)

NOTE: BPSK mode is used for the plots in this figure; as such, I and Q are inverse of each other.

The receive In-phase and Quadrature (I and Q) signals are the demodulated lowpass-filtered data that are coupled to the HFA3861. The output levels of these two signals are approximately 500mVP-P. As these are balanced signals, data is taken using a Tektronix P6247 Differential Probe.

• Test point K for RXI+ signal is at the 0Ω jumper, R19.

• Test point K1 for RXI- signal is at the 0Ω jumper, R23

• Test point L for RXQ+ signal is at the 0Ω jumper, R27

• Test point L1 for RXQ- signal is at the 0Ω jumper, R29.
