Rx SIGNALS - In Standby Mode
Signal from PAC to SMOC.
When PA is at or near saturation signal is low, telling SMOC to reduce AOC drive
When the PA is not near saturation this is high, telling SMOC to increase AOC drive.
Signal from the SMOC to the PAC
When this signal is low, the internal gain in the PAC is unity.
When this signal is high, the internal gain in the PAC is 1.
From uP to PAC.
This is a timing signal to the PAC to provide the current path for the initial loop precharge
Signal from SMOC to PAC.
This is a linear control voltage for ramp up and ramp down of the PA output level.
This controls the voltage on the exciter control output (EXC) from the PAC.
EXC
Signal from uP but inverted via Q501 and used to time:-
1. GIF SYN 2. TX VCO 3. PAC
4. RF Switch
Enables Tx Path when high
Signal from uP inverted via Q502.
Enables TIC, PA and TX VCO.
When high, this enables Tx path.
From SMOC IC to GIF SYN
This signal is the in-phase input to the I-Q Modulator of the GIF SYN.
From SMOC IC to GIF SYN
This signal is the quadrature input to the I-Q Modulator of the GIF SYN.
From uP to SMOC.
This signal indicates when the uP is reading data from the SMOC. High when enabled.
From uP to SMOC.
This signal indicates when the uP is writing data to the SMOC. High when enabled.
From uP to SMOC
This is an interrupt from the uP to the SMOC. When high this indicates to the SMOC the
beginning of the receive burst.
From uP to GIF SYN
Signal to drive the GIFSYN IC. This is a pulsed signal which controls the sending of SPI data
to the GIFSYN for all RF functions.-
From GIF Syn to SMOC IC.
This is a baseband analogue signal to A/D convertors of SMOC
From GIF Syn to SMOC IC.
This is a baseband analogue signal to A/D convertors of SMOC

Put the phone in test mode and key in commands: 110062#, 262000#, 25013#, 241#. Test for a set level eg. (-30dB’s) at point ____to compensate
:
The only real short-cut we can take is by probing the 215MHz test point (pin 31of GIF or point_____
.
)
- If, as in most cases the
215Mhz is low
there is no choice but to remove the LNA/MIXER can (
SH402
) and probe the R.F inputs to the Mixer to see
-
If 732.4 is low
, and 947.4 is OK, the main suspicions are with the main VCO and this can should be removed (
SH201
)
-
If 947.4 is low
, and the 732.4 OK, the main suspicions are with the input filter FL452 and this can (
SH402
) should be removed, and if low
at the input to these, it could be losses caused by the Rf Switch (U401).
- If
947.4 and 732.4 RF values are fine but 215MHz into GIF is low
____ then we must also remove can covering filters (
SH401
) as SAW filter
(FL420) and IF Pre AMP (Q421) is located under here.
-
If the 215 is OK
then we can assume problem lies around GIF, either 430MHz Local Oscillator or in generation of
RXI
and
RXQ
. The peel off can
SH202
should then be removed. Check that
IQ Ref
from the SMOC is around 1.38Vdc and then the
RXI and Q
outputs from the GIF to check which is
faulty. Before actually removing any cans it may be worth checking the
RX_EN
and
RX275
lines at points

If 732.4 is missing but 170 is fine
remove

If both 732.4 and 170 are missing
